Tóm tắt

This study reports on removal of lead and cadmium ions from aqueous solution by adsorption principle based on polyaniline sawdust composite. Their concentrations in solution before and after adsorption process were analysed by Atomic Adsorption Spectroscopy (AAS). Results indicated that the maximum adsorption capacity was found 188.6792 mg/g for cadmium ion onto composite prepared by soaking method and 303.0303 mg/g for lead ion onto which prepared by direct polymerization. Adsorption capacity analysis explained that adsorption of Pb2+ and Cd2+ is favourable and fitted well into Langmuir better than Freundlich adsorption isotherm model.
