TRACE LEVEL REMOVAL STUDIES OF CR(III) FROM AQUEOUS SOLUTION
ABSTRACT A flame atomic adsorption method was employed to study the removal of Cr(III) from aqueous solution onto bentonite surface, using the batch equilibrium method. Maximum removal (98.7%) was achieved from a solution of pH 2.5. Effect of various parameters like concentration, shaking time and temperature were also examined to achieve the optimized conditions of maximum recovery of Cr(III) from solution by adsorption method. The presence of various anions and cations on the adsorption behavior of Cr(III) were also investigated. The data was also investigated in terms of calculating thermodynamic quantities and also fitted well to Langmuir's equation.
