Abstract


This study aimed to investigate the application of chitosan-g-poly(itaconic acid)(CS-g-PIA) adsorbent for the dispersive solid phase extraction (dSPE) of copper (II) ion(Cu2+) and lead (II) ion(Pb2+)in water sample. The synthesized adsorbent was characterized by Fourier Transform Infrared Spectroscopy (FTIR) and Brunauer Emmet Teller (BET) analysis. Flame Atomic Absorption Spectroscopy (FAAS) was used to determine the amount of Pb2+ and Cu2+ after dSPE.The optimum extraction method parameters wereas follows: water sample pH 6, 100 mg of adsorbent, extraction time of 30 min, sulphuric acid as desorption solvent and desorption time of 7.5 min.The optimized method showed linearity with R2 of 0.973 and 0.998 for Pb2+ and Cu2+, respectively.  Furthermore, the limit of detection (LOD) values were2.93mg/L and 0.12 mg/L for Pb2+ and Cu2+, respectively.
