The driving force of the transportation is differences ofconcentrationofhydrogenion between feed phase and stripping phase.
料液相与回收相溶液之间的氢离子浓度之差是镉离子迁移的动力；
2
Using the definition and calculation formula of distribution coefficients, the deduction of the hydrogenionconcentration in solutions will be simple, clear and exact.
利用分布系数的定义和计算公式推导溶液的氢离子浓度，该方法思路简单、明了、求解准确。

However, there is only a moderate correlation between the hydrogenionconcentrationof a food and its perceived sourness due to the penetration of non-dissociated acids inside the taste cells.
