Development and Application of Chromatographic Gray Model(Ⅳ)--Establishment of CGM(1,1, N) Model and Prediction of Retention Behavior of Isomeric Alkylbenzenes

Abstract

Abstract: We derived the N-parameter gray model--CGM(1,1, N) based on gray system theory in this paper. The complicated relationships between chromatographic retention be-havior of isomeric alkylbenzenes and molecular structure parameters have been successfully investigated using the gray model. The retention and the logarithm of the partition coefficient of isomeric alkylbenzenes have been predicted. The precision is higher than that of the single parameter model--continuous gray model CGM(1,1). CGM(1,1, N) is a practical method for the prediction of the retention behavior of solutes.
