Description method is described for the recovery of NHa99TcO,, from its reaction waste. From the collected waste solution 99Tc was precipitated as 99Tc2S' 7 which on digestion with ammoniacal hydrogen peroxide produced a mixture of NH499TcO4 and (NH#2SO 4 from which the latter was removed by treatment with Ba(OH)2. The solution furnished NH49 TcO 4 as a crystalline material in 54% overall yield and with 96--98% purity after chromatographic purification over Dowex 50W column. Recrystallisation of this material from aqueous ammoniacal ethanol gave the analytical material which compared well with a standard sample and with literature data in terms of its I~-counts/mg and its molar extinction co-efficients (~:) at 244 and 286 nm.
