Abstract
This research addresses the development of stable green ELM process for chromium removal from industrial effluents where CrO4 2− and Cr2O7 2− is the predominant species. Types of carriers, diluents and stripping agents undergo screening via LLE process. Meanwhile, the parameters studied for ELM stability and extraction were surfactant and modifier concentrations, homogenizer speed and emulsifying time. The formulate condition of stable ELM process was 0.04 M TOMAC in palm oil, 0.05 M NaOH, 3% (w/v) Span 80, 5% (w/v) octanol, 10,000 rpm homogenizer speed and 3 min emulsifying time. At this condition, 97% of chromium was extracted with breakage rate of 10%.
