ELECTRON-IRRADIATION STUDIES ON AMMONIUM MOLYBDOPHOSPHATE

Ammonium molybdophosphate (AMP) was irradiated with electrons up to a dose of 1 MGy. X-ray diffraction patterns and FT-IR of irradiated and control AMP samples were recorded. Uptake of Cs-137 from nitric acid i n the range of 0.2 to 10 mol . dm(-3) was estimated by a batch equilib ration technique. AMP undergoes perceptible changes in its physico-che mical characteristics on irradiation with electrons. Uptake of Cs-137 from nitric acid by irradiated AMP was nearly the same as the control AMP in the nitric acid concentration range of 6 to 10 mol . dm(-3) and relatively higher in the range of 0.2 to 6 mol . dm(-3). The results are discussed in terms of available information on the physicochemical properties of 12-heteropoly acids and their salts.
