SEQUESTRATION OF ZINC ION USING SUGAR INDUSTRY RESIDUES: AN AVENUE TO ENVIROSAFES. KARTHIKA AND N. MUTHULAKSHMI ANDAL
The present study focuses on the removal of zinc from aqueous solution utilising a sugar industry residues (untreated) as an adsorbent. Adsorption experiments were performed by following batch techniques, sorption capacity of the adsorbent determined as the function of pH, initial concentration of the metal solution, contact time and particle size. Various kinetic parameters were evaluated using the observed experimental data from different techniques. The morphological investigations were carried out using Scanning Electron Microscope (SEM), Energy Dispersive Xray Spectrometer (EDAX). The results indicate that the sugar industry residues, a new cost effective industrial based sorbent material holds great potential for the extraction of Zn(II) from the aqueous solution with maximum removal of 95.55% at pH value of 5.
