Standard methods for analysis of phosphorus-32
Methods are described for the determination of the radiochemical purity and the absolute disintegration rate of /sup 32/P radioisotope preparations. The /sup 32/P activity is determined by ..beta.. counting, and other low-energy ..beta.. radioactive contaminants are determined by aluminum-absorption curve data. Any ..gamma..-radioactive contaminants are determined by ..gamma.. counting. Routine chemical testing is used to establish the chemical characteristics. The presence or absence of heavy metals is established by spot tests; free acid is determined by use of a pH meter; total solids are determined gravimetrically by evaporation and ignition at a temperature sufficient to evaporate the mineral acids, HCl and HNO/sub 3/; and nonvolatile matter, defined as that material which does not evaporate or ignite at a temperature sufficient to convert C to CO or CO/sub 2/, is determined gravimetrically after such ignition.
