摘要: AbstractIn order to effectively utilize agricultural wastes, the feasibility of using a novel calcined composite dolomite, montmorillonite, and corn stover for removing chromium(VI) from aqueous solutions was examined. Batch experiments were conducted investigate effect dosage, solution pH, initial concentration chromium(VI), temperature during removal process. Chromium(VI) efficiency increased with increase in amount but remained almost unchanged (84–86%) when pH 2.0 11.0. The 20 40°C indicated that high favored This conclusion also confirmed by adsorption energy evaluation where reaction process found be endothermic spontaneous. well fitted pseudo-second-order kinetic model. Fitting experimental results intraparticle diffusion model revealed tha...
