Abstract:
The present invention discloses a method for determination of magnesium content in aluminum alloy, including: dissolving an aluminum alloy sample, using one or more compounds selected from the group consisting of mercapto-containing compound, acetone cyanohydrin, β-aminoethyl mercaptan, triethanolamine, tetraethylenepentamine, ethylene diamine and oxydol as masking agent, using eriochrome black T or methyl thymol blue as indicator, and using EDTA or CDTA to titrate the sample.
