Abstract

We report a new modification of composite beads to absorb metal ions. The phosphate insertion into the activated carbon coated with chitosan is expected to have a higher adsorption capacity and the better mechanical properties than activated carbon and chitosan respectively. The identification of the adsorption ability of the composite beads was carried out at various contact times between the adsorbent and metal ions (Mg2+ and Pb2+) using a batch system. Furthermore, the beads are regenerated using Na2EDTA. Characterization of beads is carried out using a Surface Area Analyzer (SAA), Fourier Transform Infrared (FTIR) and Transmission Electron Microscope (TEM). Concentration of metal ions was determined using Atomic Absorption Spectroscopy (AAS). The characterization of composite beads of activated carbon-phosphate-chitosan showed that the beads had a spherical morphology with a measure of activated carbon on a nano scale (<100 nm) and a surface area of 0.01176 m2/g. The composition of chitosan and phosphate in adsorbent is supported by FTIR spectrum absorption peaks, namely N-H, -OH and P-O bonds. The composite beads have adsorption capacity for both Mg2+ and Pb2+ ions which is almost the same, which is ~11 mg/g with the contact time to the analyte relatively constant of ~150 minutes. The identification of regeneration beads with Na2EDTA shows that the adsorbent has been potential to be reused.
