Chitosan coated on a polypropylene fabric enhances the mechanical stability and reduces gel forming behavior of chitosan. Chitosan coated on H2SO4 treated polypropylene fabric and cross linked with glutaraldehyde was used for the preparation of filter. The quantity of the chitosan coated PP fabric was studied using thermo gravimetric analyzer. The Adsorption studies of Cd(II), Zn (II) ions was carried out in a batch process at room temperature in static manner with varying all possible parameters such as pH of solution, adsorbent concentration, metal concentration etc. Metal concentration was measured using ICP AES. It has been shown that CS coated PP fabric is an excellent adsorbent for heavy metals and a filtering unit may be fabricated using this technology at lower expenses.
