APPLICABILITY OF THE METHODS OF MATHEMATICAL SPECTROPHOTOMETRY FOR RAPID-DETERMINATION OF GA, PB, TE, IN, B, CU, AND AL USING THE NONSELECTIVE ORGANIC REAGENT P-NITROPHENYLFLUORONE

The applicability of methods of multidimensional statistical analysis for quantitative determination of a number of components in an anodic alloy formed in electrochemical purification of aluminum was studied. The content of aluminum, gallium, indium, copper, and lead was estimat ed without preliminary separation and with their simultaneous presence . The group reagent of a boron complex of p-nitrophenylfluorone in a s lightly alkaline medium was used as a reagent. The calculations were p erformed using program packages compiled by the author that realize th e procedures of abstract and plan-factor analysis.
