REMOVAL OF CHROMIUM HEXAVALENT IONS FROM AQUEOUS SOLUTION BY RETENTION ONTO IRON PHOSPHATE

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 isoth...
