- Abstract
In this present work, the modified chitosan composite is prepared by using Alumina and Silica. The prepared composites are characterized by SEM, EDAX, XRD and FTIR techniques. The physiochemical characteristics such as Carbon Yield (%), Moisture content, pH, Acidity and Basicity, Zero point charge, Boehm’s titration, Iodine number are also carried out. The yield and iodine number of chitosan modified silica 91.6% and 2743.555mg/g is higher than the chitosan modified alumina 85.2% and 2121.457mg/g. The prepared composites are used as remarkable adsorbents in the treatment of wastewater due to its biodegradable and non-toxic nature.
