In the past research, many assumptions are usually used to simplify the problem, which is result in failing to approach the reality. However, in the past few years, more and more theories are proposed, which are in order to fit in with the cases in reality. In the present research, we assume a charge-regulated system which is able to pertinently simulate the surface property of colloidal particle closing to reality. On the other hand, in the liquid phase, we adopt a multiple ionic species system which is more close to the reality especially in high/low pH. In the research, we suggest that the result from adopting multiple ionic species liquid system is differ from that from adopting traditional two ion species liquid system under some particular circumstances. In the latter part, we discuss the temperature dependence of parameters and diffusiophoresis behavior. The result indicates that as temperature increase, the diffusiophoresis mobility is influenced in different extent.
