Unformatted text preview: d Lutfor Rahman, Sazmal Effendi Arshad and Noumie @ Loumie Surugau School of Science and Technology, University Malaysia Sabah, 88999 Kota Kinabalu, Sabah, Malaysia E-mail: simonssyw@yahoo.com A new stable chelating ligand containing the hydroxamic acid and amidoxime functional groups was synthesized from the poly(methyl acrylate-co-acrylonitrile) grafted acacia cellulose by using ceric ammonium nitrate (CAN) as initiator through free radical initiating process. Conversion of ester and nitrile groups of the grafted copolymer into the hydroxamic acid and amidoxime was carried out with the reaction of grafted copolymer with hydroxylamine under alkaline condition. The optimum grafting yield was determined during the optimization of amount of added acacia cellulose, mineral acid, CAN, MA and AN at 0.062, 0.120, 0.016, 0.397 and 0.550 mol/L respectively. The poly(MA -co-AN) grafted cellulose was obtained at 55 °C after 2 hours stirring. Then the purified grafted cellulose and chelating resin were characterized by FTIR Spectroscopy and TG analysis. The chela ting behaviour of the prepared resin was carried out by the adsorption of metal ions on resin. The metal ions -sorption capacities of the resin were pH dependent and its selectivity towards metal ions was in the order of 2+ 3+ 3+ 2+ 2+ Zn >Fe >Cr >Ni >Cu . The rate of exchange of copper ion was very fast showing t 1/2 =5 min. The heavy metal recovery was found to be highly efficient, where up to 99 % of the metals could be removed from metal plating wastewater using column method. ENV-O14 APPLICATION OF UF MEMBRANE FOR TREATMENT OF PALM OIL MILL EFFLUENT: EFFECT OF TRANSMEMBRANE PRESSURE Munirat Idris Oseni, Mohammed Saedi Jami and Suleyman Aremu Muibi Department of Biotechnology Engineering, Faculty of Engineering, International Islamic University, Malaysia E-mail: saedi@iium.edu.my This study is an effort to evaluate the performance of polyethersulphone UF membrane in the treatment of palm oil mill effluent (POME) waste by varying the transmembrane pressure. Flat sheet polyethersulfone (PES) ultrafiltration membrane of molecular weight cut-off (MWCO) 1 kDa was used in this study. Biologically treated POME was first subjected to physical pretreatment processes, consisting...
