The ability of chemically modified sugarcane bagasse for the removal of Cr (VI) from aqueous solution was investigated as a function of change in pH at temperature 28±1oC, concentration 1.987×10-4 M and particle size < 55 mm. The adsorption of Cr (VI) on chemically modified bagasse (MB) was nearly 8% higher against unmodified bagasse (UB). The acidic pH of the medium promoted the rate of Cr (VI) adsorption on the adsorbent while inhibited at neutral or alkaline pH and gave good fit for adsorption kinetics equation.

Abstract


The ability of chemically modified sugarcane bagasse for the removal of Cr (VI) from aqueous solution was investigated as a function of change in pH at temperature 28±1oC, concentration 1.987×10-4 M and particle size < 55 mm. The adsorption of Cr (VI) on chemically modified bagasse (MB) was nearly 8% higher against unmodified bagasse (UB). The acidic pH of the medium promoted the rate of Cr (VI) adsorption on the adsorbent while inhibited at neutral or alkaline pH and gave good fit for adsorption kinetics equation.
