Adsorption of Chromium (VI) from Wastewater Using Blended Natural Adsorbent

Abstract

In this study adsorption of chromium (VI) ion by using blended natural novel adsorbent like neem leaves powder with peanut shell powder. The batch Adsorption experiments were conducted by different proportions of blended neem leaf powder and peanut shells powder and variations in the weight of adsorbents, contact time at room temperature, and various pH. Investigate the concentration of adsorbate before adsorption and after adsorption by 1, 5 Diphenyl Carbazide Colorimetric method with reference to calibration curve. Results obtained by blended neem leaves powder with peanut shell powder adsorbent are more effective at pH 6. Removal of efficiency increases with increasing contact time and dosage of adsorbent. This adsorbent is low cost and readily available in nature.
