THE SYNTHESIS OF SEVERAL ESTERS OF MERCAPTOASETIC ACID AND ITS INVESTIGATION AS REAGENTS FOR DETERMINATION OF Co(II) IONS CONTENT IN AQUEOUS MEDIUM

P.G.Asadova, Z.G.Huseynov, P.R.Mamedov

Cited are the results of investigation on synthesis of the several esters of mercaptoasetic acid and study of their complex formation properties with Co(II) by spectrophotometric method. The optimal conditions of the complex formation have been revealed. At pH equal to 9, the maximum of light-absorption of complex correspond to 560 nm. The molar coefficient of light absorption of complex make up 5.7×10⁴
