Abstract. The process of heavy metals adsorption by natural mineral palygorskite from wastewater and food (apple juice) has been investigated. The purification processes of copper, cadmium, lead, mercury and zinc have been studied. The rational technological parameters of these processes have been determined. The mechanism for heavy metals adsorbtion from juice by palygorskite has been defined.

Abstract. 1The conditions of the immobilization of xylenol orange, methylthymol blue, pyrocatechol violet, and chromazurol S at the surface of AB-17×8 anionite were studied. The interaction of Cu(II), Pb(II), Zn(II), Hg(II) ions with obtained solid-phase reagents was investigated. The efficiency of the purification of apple juice with such natural adsorbent of Cherkasy deposits (Ukraine) as palygorskite was studied. The optimum conditions of the reactions, quantitative characteristics of the composition and the surface compound stability, the efficiency of the anion exchanger with the immobilized sulphophthalein dyes were determined.
