Iron phosphate was synthesized and characterized for the removal of Cr(VI) ions from aqueous solution. Batch type experiments were conducted to study the effects of contact time, pH of the solution, chromium concentration and temperature. The experimental data were analyzed with the adsorption isotherms models of Freundlich, Langmuir and Dubinin Radushkevich (D-R). Results showed that Cr(VI) retention is dependent on pH and temperature. The thermodynamic parameters of the retention system were determined in a temperature interval from 293-323 K. The obtained values of thermodynamic parameters show that the Cr(VI) ions retention on iron phosphate is endothermic and spontaneous type. The results suggest that iron phosphate could be used as an effective adsorbent for the retention of Cr(VI) ions from aqueous solution.
