Abstract:
Due to the perlite s remarkable properties, we used it in this paper as absorbent material for separating the Pb2+ ions from aqueous solutions. We studied the influence of different parameters on the separation process, such as: absorption time, perlite dosage, the pH of the separated solutions, initial concentration of Pb2+, temperature. An efficient separation of the Pb2+ was achieved by shaking the solutions for 11 minutes, at optimal pH 5, using a perlite dose of 0.5 grams, initial concentration of the Pb2+ ions of 10 mg/dm3 at a temperature of 35°C.
