Abstract
Abstract An important aspect of the influence of specific surface area of adsorbent on RM values of substances obtained in the process of adsorption thin-layer chromatography has been presented in the paper. The experiments have been conducted with four adsorbents, each having different specific surface area, that is, from 50 to 500 m2/g and with the use of mixed binary solvent mobile phases of benzene-aliphatic alcohol type. It has been proved that RM values of investigated substances of group B change regulary according to the specific surface area of adsorbent for individual concentrations of mobile phase. The relationship may be described by means of square trinominal. The parameters of trinominal may be tabulated and the differentiation of the parameters for particular substances is observable at the same time. The relationship in question may be utilized to calculate RM, values of studied substances on any adsorbent with known specific surface area.
