Speciation Capability of Chromium Ions by TLC

Selective determination of chromium (III) and chromium (VI) by ion exchange TLC is described. Optimal separation and selective determination were obtained using the plates with with 10 % of solid anion exchanger and the solvetnt system methyl - isobuthyl ketone :H3PO4 (1mol/dm3) : KCN (1 mol / dm3) : acetic buffer : EDTA (0.1 mol / dm3) in 1:2:10:9:1 ratio. Selective determination Cr(III) and Cr(VI) using the plates with 23 % of cation exchanger and 1.5 mol / dm3 HCl is also suitable
