Paper Title
Separation And Identification Of Toxic Heavy Metal Ions By Thin Layer Chromatography
Abstract
-Thin layer chromatographic method has
been developed for the separation of metal ions such
as Cr (VI), Cr (III), Ni (II), Co (II), Cu (II),Fe(III), Zn
(II) and Mo (VI)from their two, three and four
component mixtures.Silicagel- G is acting as an good
adsorbent so various separations were performed on
thin layer of silica gel G using aqueous humic acid
and DMF ie - dimethylformamide as a mobile phase.
The effect of concentration and pH of mobile phase
on the Rf values of individual metal ions were studied
and the optimum conditions for separation of metal
ions from their mixture were determined. By using
surfactant and with various additives mixed in mobile
phase, metal ions such as Cu2+
, Cr
+6
and Co2+
, Ni
2+
were separated from their binary mixture
