dc.description.abstractThe unique properties of chitosan such as adsorption, non-toxicity, porosity, polyelectrolytic nature and polyfunctionality make it an ideal cost effective bioadsorbant for heavy metals. As the degree of deacetylation (DDA) of chitosan largely affects its properties, a study was carried out to compare heavy metal (Cd and Pb) adsorption efficacy of chitosan of different DDA (78.2, 86, 90.2 & 94.2 %) in flake and bead form. SEM images and FT-IR spectra revealed the characteristics of flakes and beads studied. Heavy metal concentration was determined using ICP-OES. At pH 7 flake and bead having DDA of 90.2 exhibited maximum removal efficiency of Cd. While in the case of Pb removal efficiency flake (78.2 DDA) and bead (78.2 & 86 DDA) types were higher. Maximum efficiency of flakes was observed at contact time of 60 min and at an initial concentration of 5 mg/L, but it was varying between bead types.en_US
