Hexavalent chromium, emanating primarily from the electroplating industries, can be reduced to the less toxic trivalent variety by several methods, including emulsion liquid membrane (ELM). In this work, studies on the continuous removal of chromium from authentic electroplating wastewater by ELM are reported. The effects of treat ratio, external feed phase, and stripping agent concentration were examined A math. boundary breakage model was used to study the extraction efficiency of chromium through the ELM process. The model representing the prediction of ELM extraction performance for chromium was validated through the comparison between the simulation and exptl. results. The result showed the simulation model is found to be in good agreement with the exptl. result. Almost 100% of 40 ppm chromium in the external feed phase was extracted within 3 to 5 min using 0.022 M TOMAC as extractant, 1.0 M acidic thiourea in the internal phase, and 1 to 5 of treat ratio. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Reference of 5137-55-3).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Reference of 5137-55-3
