主要研究结果如下：在测试pH条件下，砖红壤悬液中正电荷密度占到负电荷密度的40 -80 %，赤红壤悬液中为8.4 - 22 %，红壤悬液为1.6 - 6.4 %；在红壤悬液中可以忽略正电荷的影响。

In this part, the densities of sodium benzoate, sodium nitrobenzoate, sodium chlorobenzoate and sodium methylbenzoate in DMFwater mixed solvents have been measured at 298.15K with an Anton Paar Model 55 densimeter. From these densities, apparent molar volumes and partial molar volumes have been calculated, transfer volumes from water to DMF-water mixtures and substituent contributions to the transfer volumes have also been obtained. Solvent and substituent effects are discussed in detail. The Scaled Partical Theory has been applied to the ternary solutions to evaluate the partial molar volumes of cavity formation and the volumes change associated with solute-solvent interaction.
