Abstract—This work presents the extraction of lead (II) from wastewater of battery manufacturing (trace concentration) using hollow fiber supported liquid membrane (HFSLM). There are polypropylene as supporter, D2EHPA as carrier, kerosene as solvent and HNO3 as stripping agent. The experiments were performed as various conditions such as organic phase concentration, stripping phase concentration, feed pH, and volumetric flow rate of feed and stripping solutions to obtain the best condition and to give the maximum efficiency. The extraction and stripping percentage of lead (II) from aqueous feed and stripping phase are 99.40% and 97.15%, respectively. The values of extraction equilibrium constant (Kex), distribution ratio (D), permeability coefficients (P) were determined. The concentration of lead (II) is measured by Atomic Absorption Spectroscopy (AAS).
Index Terms—Hollow fiber, liquid membrane, lead extraction, battery manufacturing wastewater.
