METHOD FOR DETERMINING IODATE- AND IODIDE-ION PROPORTION IN SODIUM IODIDE PREPARATIONS AND PROCESS WATER USED FOR ISOTOPE PRODUCTION Russian patent published in 2000 - IPC

FIELD: chemistry and primarily analytical chemistry. SUBSTANCE: method primarily used for quality control of NaJ¹²⁵,NaJ¹³¹ base preparations as well as for investigations concerned with cleaning process water and waste gases from radioactive iodine in isotope production processes, that is, for determining iodate- and iodide-ion proportion involves following operations. Iodate- and iodide-ions are separated into fractions using ion chromatography method involving background suppressed on styrenedivenylbenzene sorbent HIKS-1 using weakly alkaline buffer carbonate solution as eluent and sample thinner, introduction of carrier solution containing stable-iodine base iodate- and iodide-ions, measurement of fractions accumulation time and specific activity of and radionuclides in fractions obtained. EFFECT: improved proximity and accuracy of analysis. 1 dwg, 2 tbl
