Abstract

The kinetics of the removal of toxic hexavalent chromium (Cr6+) from acidified potassium dichromate solution using iron cylinder as reducing agent was studied. The effect of the presence of different organic acids (e.g., acetic acid, chloroacetic acid, dichloroacetic acid, trichloroacetic acid, sulphosalicylic acid, citric acid and phthalic acid) upon the reaction was investigated. It is found that the presence of organic acids decreases or inhibits the rate of the reduction reaction. The percentage inhibition in the presence of organic acids was ranged between 62.33 and 79.82 % at 25 °C, indicate that, increasing of organic additives concentrations is followed by increasing in inhibition power and this could be due to decrease in the diffusion coefficient values of the solution containing organic acids. Also the rate of reduction was found to increase by increasing the temperatures. The factors studied were, the concentration of the organic acids and speed of rotating iron cylinder. The applicability of the adsorption process to the Langmuir, Florry-Huggins and kinetic-thermodynamic isotherm was delaminated.
