The Use of Sulphophtalein Dyes Immobilized on Anionite AB-17x8 to Determine the Contents of Pb(II), Cu(II), Hg(II) and Zn(II) in Liquid Medium
The conditions of the immobilization of xylenol orange, methylthymol blue, pyrocatechol violet, and chromazurol S at the surface of AB-178 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.
