Abstract

The solvent extraction chemistry of the oxinates of aluminium, iron, chromium, and nickel have been studied, particularly that of aluminium. Conditions for the quantitative analytical determination of al-uminium by extraction of its oxinate have been put forward. Investigations have been made to incorporate this method in the analysis for aluminium, in steels containing iron, chromium and nickel as interfering elements. A number of complexing reagents were studied in order to remove the interference of these elements. A limited success only was achieved. Spectrophotometric measurement of the absorbance of U.V. light at 390 mμ. has been found the most suitable method for determining trace quantities of al"uminium oxinate.
