摘要：
Adsorption of Cr (VI) as CDC-complex from aqueous solution by activated C has been investigated. Factors like pH and presence of Cr (III) which affect the adsorption of CDC-complex were studied. The increase in particle size and surface area of activated C does not enhance the removal of CDC-complex. For different concentrations of Cr, the optimum quantity of Diphenyl Carbazide has been determined. The reduced Cr e.g. Cr (III) decreases the CDC-complex removal. The Langmuir and Freundlich isotherms constant as calculated are GAMMAm = 1.8932 and b = 0.2305 and n = 0.036, log K = 0.0266, respectively.
