	Abstract:Cadmium (Cd), lead (Pb) and hexavalent chromium (Cr(VI)) often appear simultaneously in the soil and water influenced by metal smelting, chemical manufacturing and electroplating. In this study, synthetic iron sulfide nanoparticles (FeS NPs) stabilized with carboxymethyl cellulose (CMC) were utilized to remove Cr(VI), Cd and Pb from aqueous solution. Batch experiments, Visual MINTEQ model and XPS analysis were used to determine the removal efficiencies, influencing factors and mechanisms. FeS NPs suspension could remove Cr(VI), Cd and Pb simultaneously from aqueous solutions with removal capacities of Cr(VI), Cd and Pb of up to 418, 96, 585 mg per gram of stabilized FeS NPs and with final concentrations of 2.5, 0.1 and 0.1 mg/L at initial concentrations of 50, 10 and 50 mg/L, respectively. The acidic conditions significantly favored the removal of aqueous Cr(VI), while the alkaline conditions favored the removal of Cd and Pb. Oxygen would slightly inhibit the removal of Cr(VI), and there was no significant influence on that of Cd and Pb. A potential mechanism was proposed for the simultaneous removal of Cr(VI), Cd and Pb by using FeS NPs. Interactions of the three heavy metals involves the cationic bridging effect of Cd to promote the adsorption of Cr(VI), the enhanced adsorption effect to Cd by Cr-Fe-hydroxides, and the enhanced precipitation to Pb by chromate and sulfate. Therefore, FeS NPs have a high potential for the simultaneous removal of Cr(VI), Cd and Pb from the contaminated aqueous solutions.

	Abstract:Removal of iron in hydrometallurgical processes is a quite popular challenge, and the traditional methods such as precipitation may cause severe secondary pollution and resources waste. In present study, we attempted a cheap and effective technique to remove the iron ions by adsorption onto garlic residue gels. A simple chemical modification method to modify the peel by calcium hydroxide was proposed. Results showed that the optimal equilibrium pH is about 2.5 for 90 % adsorption without the hydrolysis of Fe(III). Adsorption equilibrium was attained within 60 min. The adsorption process can be described well by Langmuir model and pseudo-second-order kinetic equation, respectively. The maximum adsorption capacity for Fe(III) ions was found to be 1.4 mol/kg. The sulfenic acid, pectic acid, polyphenolic and alliin components contained in the garlic peel are inferred to be the main ligands responsible for the uptake of Fe(III) ions onto the gel. The simulated solutions referring to the hydrometallurgical process of nickel and copper were prepared to test the selective removal behavior of Fe(III), and the possibility of recovery and reuse of the adsorbed iron was also discussed. The present work may help to recycle and reuse the huge amount of iron resources in the real hydrometallurgical processes, and also bring a more ecofriendly, cleaner and shortened process for many traditional hydrometallurgical processes.

	Abstract:In this paper, the adsorption of uranium by graphene oxide was investigated. The effect of pH, contact time, concentration of uranium and temperature on the adsorption capacity of uranium was determined. The graphene oxide (GO) was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and infrared spectra (FTIR). FTIR spectra indicated that carboxyl and alkoxy groups existed on the surface of GO, which involved in uranium adsorption. The adsorption kinetics of U(VI) followed pseudo first-order kinetic model. The adsorption isotherm conformed to Tempkin model. The adsorption process is spontaneous and exothermic.
