Amberlite IR-400 was chemically modified using titan yellow as a chelating agent. Adsorption studies such as effect ofconcentration, pH, time and temperature on the resin has been studied. Distribution coefficient studies of metal ions invaried solvent systems have been explored. On the basis of Kd values, important binary as well as ternary separationsViz. Mn2+-Hg2+,Zn2+-Hg2+,Mg2+-Bi3+,Cu2+-Hg2+,Pb2+-Sn4+,Pb2+-Bi3+ & Cd2+-Hg2+,Ca2+-Hg2+-Zr4+,Cd2+-Hg2+-Co2+,Ni2+-Hg2+-Co2+,Pb2+-Hg2+-Co2+ and Ce3+-Hg2+-Co2+ has been achieved on columns of titan yellow modified Amberlite IR-400resin. In order to check the selectivity and reproducibility of the method, different amounts of Hg2+ has been loaded insynthetic mixtures containing (Mg2+=2.43mg),(Ca2+=4.01mg),(Ba2+=13.74 mg), (Sr2+ =8.76 mg), ( Pb2+= 20.72mg),(Zn2+= 16.54 mg),(Cd2+=11.24 mg). This material can be utilized for the removal and isolation of Hg2+ from wastewater produced from industrial units.
