Rapid complexometric analysis of brass with CTDA.
A method for the analysis of brass is presented. The lead, iron, nickel and zinc components are determined titrimetrically with the complexing agent CDTA (disodium dihydrogen 1,2-diaminocyclohexane N,N,N',N'-tetraacetate [also known as HexaVer]). The copper and the tin are weighed as metallic copper and as stannic oxide. The method is more rapid and convenient, especially for routine analysis, than the all-gravimetric procedure and it provides at least equal accuracy and precision.
