Synthesis of adsorbent materials based on polyaniline and agriculture waste by soaking method for removal heavy metal ions from solution

ThiTot Pham, ThiThanhThuyMai, MinhQuy Bui, ThiXuanMai, Thi Binh Phan


Composites based on polyaniline (PANi) and agriculturewaste (peanut shell (PS), rice raw(RR)) prepared bysoakingmethod for removalCd2+ and Pb2+ ions fromsolution. Itwas found by IR-spectroscopy a clearly presence of PANi in composites. Their mophorlogical structurewas shown in nano range due to SEMand TEMimages. Cd2+ and Pb2+ ion concentrations in solution before and after adsorption process on those compositeswere analysed byatomic adsorption spectroscopy. Themaximumadsorption capacities of Pb2+ (185.1852mg/g) and Cd2+ (131.5789mg/ g) ions onto PANi-PS were higher than those onto PANi-RR (158.7302mg/g and 93.4579mg/g for Pb2+ andCd2+ ions, respectively).Their adsorption process occurredontobothcomposites fittedwell intoLangmuir isothermmodel also.
