	Abstract:A new and facile route has been developed to synthesize beta-Ni(OH)2 nanostructures using ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim]BF4) as reaction media under solvothermal conditions. The beta-Ni(OH)2 with different morphologies, such as nanoflakes, nanoplatelet and nanorods, can be obtained by controlling the volume ratio of the ionic liquid to water and reaction temperature. The as-prepared products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The as-prepared beta-Ni(OH)2 composite electrodes were prepared by mixing 10 wt.% samples with common spherical Ni(OH)2 to carry out charge-discharge test. The results show that the as-prepared beta-Ni(OH)2 composite electrodes have higher discharge specific capacity, and the beta-Ni(OH)2 nanoflakes show a better electrochemical performance than the others.

	Abstract:Orange peel was used as raw material to prepare two novel orange peel adsorbents MgOP and KOP. FTIR and SEM were used to characterize the adsorbents. Effects of pH, solid/liquid ratio, time and metal ion concentration on the Cu2+ adsorption were investigated by these two adsorbents. The equilibrium data were analyzed by using Langmuir, Freudlich, Temkin and Dubinin-Radushkevich models. Langmuir model provides the best correlation for the adsorption of Cu2+ by both MgOP and KOP, and the mono-layer adsorption capacity for Cu2+ removal by MOP and KOP are 40.37 and 59.77mg/g, respectively. The adsorbed amounts of Cu2+ increased with the increase in contact time and reached equilibrium within 20min. Kinetics data were analyzed using four adsorption kinetic models: the pseudo-first and second-order equations, the Elovich equation and intraparticle diffusion equation. The experimental data fit well the pseudo-second-order equation, which indicates the adsorption of Cu2+ by MgOP and KOP may follow a chemisorption mechanism. Thermodynamic studies showed the spontaneous, exothermic nature of the adsorption of Cu2+ by MgOP and KOP.

	Abstract:Being high dispersity, hydrophilic property and viscosity, bentonite is widely used in the pellet production. Hunyuan bentonite is one of large-type bentonite deposits in China, the reserve of which is more than 0.15 billion tons. However, it is a kind of typical Ca-bentonite (Ca-Bent), not completely utilized in the pellets presently. The sodium-modification of the Ca-bent is investigated by means of suspend liquid in this paper. To begin with, the process mineralogy of the sample is carried out, based on which, different factors (sodium agent and dosage, pulp density, sodium temperature and sodium time, etc.) affecting the sodium-modification are researched. The results show that the alkali coefficient K of modified bentonite is increased from 0.34 to 1.33, and the 2HWA, dilation and colloid index are respectively increased to 601%, 32.4mL/g and 87.6mL/(3g) under the optimal conditions of Na2CO3 dosage 3.0%, pulp density 20%, sodium temperature 55℃ and sodium time 0.5h. The XRD patterns of the bentonite before and after sodium-modification show the d(001) from 1.5539nm reduces to 1.2467nm, and 2θ(001) from 5.6875° increases to 7.0907°, indicating that the Hunyuan Ca-bent is effectively modified into Na-Bent. This investigation can provide a feasible route for the utilization of Hunyuan bentonite.

	Abstract:Having poor hydrophilicity, metallurgical dusts & sludge are difficult to recycle. Aiming at producing metallic briquettes for iron-making, investigations on agglomeration of metallurgical dusts & sludge with CB and its reduction roasting are studied. CB consists of organic polymer, which can improve hydrophilicity of dusts & sludge. FT-IR spectrum indicates that composite binder contains a variety of active groups (-OH,-COOH). Using the wet-grinding process, CB dosage can be decreased to 1.4%. Composite binder has the role of catalytic reduction at high temperature. Compared bentonite with the composite binder, the TFe and metallization ratio of products are increased by 2-3%. Under the conditions of roasting temperature 1275℃, and time 20 min, roasted briquettes with TFe of 64.74% and metallization ratio of 85.66% could be obtained. The residual Zn and Pb content meet the demands of iron-making.

	Abstract:The preparation of orange peel xanthate and its adsorption behaviors of heavy metals: Cu2+, Cd2+, Pb2+, Zn2+, Ni2+ were studied. FTIR spectrum and zeta potentials were used to characterize the prepared orange peel xanthate. Effects of various parameters including equilibrium pH, initial ion concentration and contact time on the adsorption processes for the five metal ions were investigated. For all five metal ions, adsorption isotherms were found to fit Langmuir model and the maximum adsorption capacities of Cu2+, Cd2+, Pb2+, Zn2+ and Ni2+ were obtained as 77.60, 76.57, 218.34, 49.85 and 15.45 mg•g-1, respectively. All adsorption processes can attain equilibrium within 20 min and kinetics was well fitted by psesudo-second order equation. It is proposed that the adsorption mechanism was complexation.

	Abstract:The method of Substance Flow Analysis (abbreviated as SFA) provides a helpful tool for the study of the industrial metabolism of a certain metal within a regional level. Lead is one of the important strategic commodities of national economic development in China. In this work the flow of lead in China, 2006, was traced within the STAF model, and the situation of production, consumption and recycling of lead resources in China were introduced. The SFA is performed on lead flows during its one year life cycle in detail, and several main average indexes from 2000 to 2006 were calculated as following: PZ=79.28%、PS=19.08%、MZ=148.91%、MS=30.25%、R＝0.8349t/t and S＝0.1949t/t. As one of the biggest producer and consumer of lead in the world, from a long-term point of view, China is still facing the problem on depletion of lead resources. How to increase the resource efficiency is a significant issue for lead industry of China. Based on the result, several advices were proposed in the paper, aiming to contribute important reference information for the industrial metabolism and resource management and recycling of lead industry in China.

	Abstract:Pristine orange peel was chemically modified by introducing sulphur groups with the carbon disulfide treatment in alkaline medium. The presence of sulphur groups on orange peel xanthate were identified by FTIR spectroscopic study. Equilibrium isotherms and kinetics were obtained and the effect of various parameters including equilibrium pH, contact time, temperature and initial ion concentration on adsorption of Pb2+ were studied by batch experiments. The maximum adsorption capacity of orange peel xanthate was 204.50 mg•g-1, which was found to increase by about 150% compared to that of pristine orange peel. The adsorption process can attain equilibrium within 20 min, and kinetics was found to be best-fit pseudo-second order equation. Temperature has little effect on the adsorption capacity of orange peel xanthate. In addition, the adsorption mechanism was proposed.

	Abstract:The present article describes the adsorption behaviors of Cu2+ and Cd2+ on chemically modified waste orange peel. The adsorbents were characterized using scanning electron microscopy and infrared spectrophotometer. The effect of various parameters like solution pH, shaking time, initial metal ion concentration and temperature on adsorption efficiencies of these two metals were studied systematically by batch experiments.. Adsorption isotherms of these two metals on orange peel and chemically modified orange peel were obtained and compared with Langmuir and Freundlich type models. The rate of adsorption of Cu2+ and Cd2+ on chemically modified orange peel at a constant temperature (25 oC) found to follow a pseudo-second order equation, indicating their chemical adsorption. Temperature has a negative impact on Cu2+ adsorption, while Cd2+ adsorption found to be more or less independent of temperature. Maximum adsorption capacities of Cu2+ and Cd2+ on the chemically modified orange peel were found to be 70.67 and 136.05 mg/g, respectively. Adsorption–desorption studies made on chemically modified orange peel showed that, the adsorption capacities remain high until 5th cycle. This study demonstrated that, the waste orange peel after simple chemical treatment could be used as a potential adsorbent for toxic metals such as Cu and Cd.

	Abstract:A temperature model for plate hot rolling is developed by using series function solution. The model is a part of mixed analytical-numerical modeling aiming at the prediction of deformation variables and microstructure evolution for plate production by hot rolling. The model takes into account the heat generated by deformation and the cooling effects resulted from hydraulic descale sprays, work roll chilling, radiation heat flux in interstand areas and on-line water cooling operations. To accomplish the continuous computation of temperatures in the whole process, compatible relationships of constants in the solutions are successfully established between passes and operations. The model is employed in the simulation of an experimental 3-passes rolling of type 304 stainless steel plate and an industrial 12-passes rolling of Q235A steel plate. The comparison of computed temperature with measured data demonstrates a favorable coincidence, which verifies the validity of the model. The application also indicates that the model can be easily employed in simulation of multi-pass rolling and other continuous operations, with a quite short computational time.
