土壤淋溶柱色谱中同系物、氯代苯保留值与流动相组成、沸点的交点规律

基于土壤淋溶柱色谱符合logk'-ψ的线性保留方程，在同系物（正构烷基苯、甲基苯）和氯代苯中，同类溶质与固定相（土壤）和淋洗剂（甲醇-水）有相似的作用方式，所以溶质保留值（logk'）与淋洗剂有机调节剂浓度间存在浓度交点，与沸点间存在沸点交点规律，并用实验进行了验证。

Intersection Point Rule for the Retention Value with Mobile Phase Composition and Boiling Point of the Homologues and Chlorobenzenes in Soil Leaching Column Chromatography

Based on the linear retention equation of the logarithm of the capacity factor (logk') vs. the methanol volume fraction ( ) of aqueous binary mobile phase in soil leaching column chromatography, the intersection point rule for the logk' of homologues and weak polar chlorobenzenes, with , as well as with boiling point, has been derived due to existence of the similar interactions among solutes of the same series,stationary phase (soil) and eluent (methanol-water). These rules were testified by experimental data of homologues (n -alkylbenzenes, methylbenzenes) and weak polar chlorobensenes.
