Abstract: | A new method for obtaining the model constants of the combined nearly ideal binary solvent/Redlich-Kister (CNIBS/R-K) equation, via least square analysis has been presented. Predictability of CNIBS/R-K in a previous method and the new one of least square analysis has been compared using some experimental solubility data sets. The results have indicated that the new method improved the predictability of the CNIBS/R-K equation about 63%. |
