COMPARITATIVE STUDY OF ADSORPTION OF Cr(VI) FROM WASTE WATER USING TAPIOCA PEEL AND BANYAN TREE ROOT

One of the most important and toxic heavy metals in wastewater is chromium. Cr (VI) is released from different industrial operations, including metallurgy, leather tanning, paint, textile industries, chemical manufacturing, pulp production, ore and petroleum refining, metal corrosion, electroplating products etc. Hexavalent chromium is toxic, carcinogenic, probably mutagenic and highly soluble. The harmful effects of chromium include lung and throat cancer. Since chromium is an important heavy metal used in various industrial processes, it finds its way into the industrial effluents causing lethal environmental hazards. The impacts of chromium on human health and the environment is matter of concern.The untreated metal containing effluents into water bodies is the most important pollution problems. Adsorption is one of the effective techniques for removal of chromium (VI) from wastewater. In the present study, low, batch adsorption is conducted using natural low cost adsorbents like Tapioca Peel (Manihot Esculanta) and Banyan Tree (Ficus Benghalensis) for the removal of chromium (VI) from wastewater. Experiment is conducted with increase in adsorption dosage. Adsorption efficiency of material will be found using UV spectrophotometer at a wavelength of 560nm. Key words—Adsorption, Batch adsorption, Chromium, Manihot esculanta, UV spectrophotometer. -------------------------------◊ -----------------------------
