Chlorpheniramine recovery from aqueous solutions by emulsion liquid membranes using soy lecithin as carrier

Résumé

Emulsion liquid membranes (ELMs) are a versatile and useful alternative for the recovery of emerging organic pollutants, such as pharmaceuticals, contained in wastewaters. These substances recently have provoked an environmental concern because of their growing detection in wastewater. In this study a methodology for CPM recovery from aqueous solutions by emulsion liquid membranes was developed, using non-toxic, natural products. The organic phase was composed of the diluents Parleam 4 or dodecane, the surfactant Abil EM 90® and the carrier soy lecithin (SL). The internal aqueous phase (stripping phase) was composed of HCl. The results show that emulsions prepared with Parleam 4 or dodecane + soy lecithin at 3% w/V + Abil EM 90® at 5% w/V as the organic phase and HCl 0.1 mol L−1 as the internal aqueous phase presented the highest extraction and recovery yields (100% and 75%, respectively) with a transfer time of 10 min.
