| Abstract: | Methods for the determination of aluminium, bismuth or copper m samples of organometallic compounds weighing 40-110 microg have been developed. Spectrophotometric determination following digestion with nitric and sulphuric acids in a sealed tube is recommended, all results obtained from the analysis of standard compounds being within +/- 0.3% absolute error. Digestion in an open tube with perchloric and sulphuric acids gives satisfactory results for bismuth compounds but erratic and often low results for aluminium and copper compounds. |
