A new microextraction approach namely electromembrane isolation (EMI) coupled with capillary electrophoresis (CE) and ultraviolet (UV) detection for determining lead (Pb) ions was developed. The EMI technique involved the use of a polypropylene hollow fiber whose channel was filled with a sodium dihydrogen phosphate/sodium tetraborate buffer solution of pH 8.1, immersed in 10 mL of an aqueous sample solution. A voltage of 300 V was applied across the hollow fiber wall for 15 min to extract Pb… CONTINUE READING
