On the possibility of using the methods of mathematical spectrophotometry for vapid determination of Ga, Pb, Te, In, B, Cu and Al by means of nonselective organic reagent n-nitrophenylfluorone

Kinetics of electrochemical machining of commercial titanium VT1-0 in halogenide-nitrate solutions was investigated. Physicochemical methods were used to determine chemical composition of soluble products resulted from titanium ionization as well as mechanism which was responsible for decrease of effective valency of titanium dissolution. It was stated that in the process of high-speed anodic dissolution of titanium. Possibility of application of multidimensional statistical analysis methods for quantitative determination of some components of anodic alloys forming in electrochemical purification of aluminium was studied. Content of aluminium, gallium, copper, indium and lead without preliminary separation was estimated when simultaneous presence took place. Boron complex of p-nitraphenylfluorone was used as a reagent in weakly acid medium. 24 refs., 2 figs., 4 tabs
