Cadmium removal from aqueous solution using vegetable oil-based emulsion liquid membrane

Cadmium removal from aqueous solution using vegetable oil-based emulsion liquid membrane / Muhammad Zamani Zakaria
Rawatan Kadmium dalam larutan akueus menggunakan cecair emulsi membran (ELM) telah disiasat. ELM berasaskan petroleum telah digantikan dengan minyak sayuran sebagai pencair untuk membran yang lebih mesra alam. Lima parameter telah dikaji: kepekatan HCl, kepekatan ammonia, nisbah fasa luar terhadap emulsi, kelajuan putaran dan masa pengekstrakan. Pengoptimuman parameter telah dikaji dengan menggunakan dua kaedah: kaedah satu faktor pada satu masa (OFAT) dan Kaedah Permukaan Sambutan (RSM). Kecekapan bagi kadah OFAT ialah 98.98% manakala kaedah RSM mencatatkan kecekapan 99.28%. _______________________________________________________________________________________________________ The treatment of Cadmium in aqueous solution using emulsion liquid membrane (ELM) has been investigated. Petroleum-based ELM was replaced by vegetable oil as the diluent for greener liquid membrane. Five parameters were studied: HCl concentration, ammonia concentration, ratio of external phase to the emulsion phase, stirring speed and extraction time. The optimization of the parameters were studied using two methods: one-factor-at-a-time (OFAT) method and Response Surface Methodology (RSM). The efficiency for OFAT method is 98.98% while for the RSM method is 99.28%.
