Description :
The adsorption of chromium (VI) ion by using blended natural adsorbent like neem leaves powder with peanut shell powder. The batch adsorption experiments were performed by blended neem leaves powder with peanut shells powder covering various parameters include weight of adsorbents, contact time, pH and volume of adsorbate solution. Calculate concentration of chromium (VI) after adsorption by 1, 5 Diphenyl carbazide colorimetric method with reference of calibration curve. In the present investigation results concluded that blended neem leaves powder with peanut shell powder adsorbent is more effective at pH 6 and removal of chromium (VI) efficiency increases with increasing contact time and dosage of adsorbent. For the adsorption of chromium (VI) ions, the Freundlich isotherm model is regarded as an appropriate absorption model with a correlation coefficient (r2) value of 0.9952. The used adsorbent is novel, low cost, eco-friendly and readily available in nature.
