THE ANALYTICAL CHARACTERISTICS OF THE IMMOBILIZATION SULPHOPHTA,LEIN DYES AT THE SURFACE ANIONITE АВ,17x8 AND THEIR USING IN ANALYSIS OF FOOD OB,JECTS

The conditions of the immobilization sulphophtalein dyes at the surface anionite АВ,found. The interaction of Cu (II), Pb (II), Zn (II), Hg (II), Fe (III), Sn (IV), Zr (IV), Ti (IV) with the surface regents was studied. The optimum conditions of the reactions, quantitative characteristics of the compo,sition and the surface compounds stability; the effective dates of the surface anionite with the immobiliza,tion sulphophalein dyes have been obtained. A new solid,phase spectrophotometric procedures was de,veloped for determination of the metal iones in the food objects.

Key words: the solid,phase spectrophotometric definition of the metal iones, the immobilization sulphophalein dyes.
