Summary: This work successfully eliminates arsenic from petroleum produced water using a hollow fiber membrane contactor (HFMC) and a blended extractant. Under optimum conditions, the extraction and stripping of arsenic achieved rates of 94.42% and 78.90% respectively. Slope analysis was used to determine the stoichiometric coefficients of synergistic interplay, and both kinetics and mathematical modelling were employed to describe the behaviors in the HFMC system. It was found that chemical reactions played a significant role in the transportation of arsenic across the HFMC, and a novel approach was adopted in studying the reaction mechanisms in a binary system.

Summary: In this study, a novel composite material, Ionic liquid Aliquat-336 impregnated chitosan microspheres (CMA), was synthesized and used for the recovery of Au(I) from thiosulfate solution. The CMA showed adjustable particle size, good hardness, and excellent selectivity for Au(I) adsorption. Various parameters including Aliquat-336 dosage, CMA size, initial solution pH, initial gold concentration, thiosulfate concentration, and temperature were investigated to optimize the adsorption performance of CMA. The results revealed that CMA exhibited high gold adsorption capacity, efficient desorption, and excellent selectivity for Au(I) in the presence of Cu-ethylenediamine-S2O32- solution. Moreover, CMA demonstrated promising application potential in the field of gold thiosulfate hydrometallurgy.
