Study of 3-methyl-5-hydroxy-5-(d-arabino-tetrahydroxybutyl)-thiazolidine-2-thione as a reagent for the spectrophotometric determination of copper.
The nature of the coppercomplex formed with3-methyl-5hy-droxy-5-(d-arabino-tetrahydroxybutyl)-thiazolidine-2-thione(MHATT) has been investigated. The complex is formed at pH 4.5-7.0, has an absorption maximum at 432 mmu, and an extinction coefficient of 13.5 x 10(3). The reaction is highly selective and the reagent has negligible absorption at 432 mmu. Simple and direct spectrophotometric methods are described for the estimation of copper in steels, aluminium alloys, lead, zinc and water, with the reagent.
