ABSORPTION OF HEXAVALENT CHROMIUM FROM TANNERY EFFLUENT USING BLACKBERRY (JAMUN) SAW DUSTS

Siddhartha Shukla, Anoop Kumar Mishra and Ajay Yadav

Abstract

Hexavalent chromium is highly toxic and used in different industries such as leather tanning, paints, wood preservation, electroplating, dye and pigment manufacturing. Cr (VI) was soluble in water and enter living cell. It can cause cancer, gastrointestinal ulcer and dermatitis in human beings. Various method have been used to remove hexavalent chromium including chemical precipitation, solvent extraction, reverse osmosis, evaporation, electrolysis, ion exchange and chemical reduction. These methods are more expensive and not suitable for small scale. The adsorption process using suitable adsorbent was effective, low-cost and innovative method to remove Cr (VI) form industrial waste water. Jamun saw dust was used as an adsorbent to remove chromium (vi). in this various parameter such as temperature, adsorbent dose, adsorbate dose, and pH were investigated.
