Abstract

The retention behavior of 36 synthetic dyes has been studied in adsorption and reversed-phase TLC on zeolite layers with n-hexane, tetrahydrofuran, and bidistilled water as mobile phases. Linear regression analysis (LRA) was used to compare the retention of the dyes when different mobile phases were used. The relationship between retention and the lipophilicity and specific hydrophobic surface area of the analytes was elucidated by stepwise regression analysis (SRA). Significant linear correlations were found between the retention of the dyes chromatographed with the different mobile phases, proving the regular retention behavior of the analytes. No linear relationship was found between the physicochemical properties of the dyes and their retention, suggesting the separation capacity of zeolite differs markedly from that of silica and silica coated with hydrophobic ligands.
