Polarographic determination of selenium in indium

Creators

Description

The procedure of determining nx10-6% Se in indium after concentrating in an elemental form on arsenic and sulphur has been developed. The selenium content is determined by inversion a.c. polarography on a sulphuric-acid background in the presence of Cu(2), potassium bichromate, and sodium pyrophosphate. 5.7x10-6% Se in metal indium has been determined by this procedure, the mean standard deviation being Sr=0.26
