Summary: Hexavalent chromium from electroplating industries can be reduced to less toxic trivalent form using ELM process. The study focused on continuous removal of chromium from electroplating wastewater, examining the effects of treat ratio, external feed phase, and stripping agent concentration. The simulation model showed good agreement with experimental results, achieving almost 100% extraction of 40 ppm chromium within 3 to 5 minutes.

Summary: This study found that Bi2S3 nanoparticles prepared from dual sulfur sources efficiently remove Cr(VI) and Cu2+ from aqueous solutions. The selectivity and stability of the removal process for Cr(VI) and Cu2+ by BS-D were excellent. The mutual promotional effects between Cu2+ and Cr(VI) during their co-removal by BS-D were attributed to electrostatic attraction and smaller pH variation.

Summary: A novel mesoporous ion exchange resin SiAaC based on a silica framework was designed and synthesized for efficient removal of Pd(II) from simulated electroplating wastewater, showing high adsorption capacity, selectivity, and reusability. The adsorption behavior of SiAaC resin on Pd(II) followed Langmuir isotherm and pseudosecond-order kinetic models, and it was proven to efficiently separate Pd(II) from wastewater through column experiments. FT-IR and XPS spectra confirmed an ion exchange mechanism between SiAaC and Pd(II). This research provides insights into the development of efficient materials for removing palladium from industrial wastewater.

Summary: The study reports a novel method of efficiently separating oil nano-emulsions using zirconia membranes with sub-100 nm pores and superoleophobic properties. The membrane fouling behavior is dominated by a combined model of intermediate pore blocking and cake filtration, with effective mitigation under high pH conditions. Overall, the zirconia membrane demonstrates high rejection efficiency for nano-sized oil droplets and consistent separation performance for real oily wastewaters.

Summary: The extraction process using an emulsion liquid membrane (ELM) has garnered interest as it efficiently removes toxic pollutants, organic and inorganic acids, and industrial pollutants with low concentrations. A comprehensive review examines ELM in terms of its characteristics, stability, and extraction efficiency, as well as the effects on membrane stability. Furthermore, a new membrane composition (green membrane) is introduced, utilizing environmentally friendly diluents and surfactants to enhance the economic and environmentally friendly standing ELM-based separation processes. The use of nanomaterials as surfactants to improve emulsion stability is also discussed.
