Effect of solution acidity, contact time, temperature, concentrate of molybdenum and tungsten in solution on adsorption performance of the resin are examined. Some parameters, such as adsorption rate constant, adsorption capacity and thermodynamics constant are determined. The influences of m(Mo)/m(WO3),contact time on separation efficiency of molybdenum from tungsten are also studied and mechanism of adsorption as well as elution are discussed. The results show that the separation efficiency of molybdenum from tungsten can reach 95% when pH=1,m(Mo)/m(WO3)=3.65×10-4,flow velocity of solution =10 mL/h and m(H2O2)/m(WO3)=0.09.Read More
