Abstract

An investigation on the separation of Pb(II) from synthetic wastewater via a hollow fiber supported liquid membrane (HFSLM) and its model is presented. Maximum percentages of Pb(II) extraction and stripping achieved were 97% and 30% using 0.03 M D2EHPA as the extractant, 0.9 M HCl as the stripping solution. The extraction and stripping of Pb(II) were second-order reaction with reaction rate constants of 0.03 and 0.19 L/mg s, respectively. A mathematical model is developed and shows that the model results fit in well with the experimental results. Average percent deviation was 3% for predictions in both feed and stripping sides.
