VISUAL TEST DETERMINATION OF ETHYLENEDIAMINETETRAACETATE
UDC 543.068.8:547.466
Keywords:
ethylenediaminetetraacetate, 1-(4-adamantyl-2-thiasolylazo)-2-naphthol, modified silica, visual test method.Abstract
The indicator system for ethylenediaminetetraacetate (EDTA) determination on the base of the complex compound of Cu(II) with 1-(4-adamantyl-2-thiasolylazo)-2-naphthol immobilized on silica surface was developed. The destruction of complex compound accompanied with the contrast color change occurs at pH 3,5 and EDTA concentration ≥ 1,0 µmol/L. The modified sorbent was shown to be promising as a ready-to-use analytical form for sorption-spectroscopic and visual test determination of 0,3–24 mg/L EDTA in highly mineralized samples, particularly in cosmetic products. The method was applied to the visual test determination of EDTA in the oxidizing emulsion for hair.
