[求助] 吸附过程包含氧化还原反应,等温线、动力学用什么模型拟合?

吸附六价铬时,包含六价铬的直接吸附,六价铬还原为三价铬再吸附的过程,我直接用langmuir和拟二级动力学进行拟合,审稿人对此提出和很大的疑问。
意见如下:
It is very surprising that the authors used a single Langmuir isotherm model to characterize the overall sorption processes(reaction between chromium(VI) and benzenoid amine followed by the chelation of chromium(III)). It is far from evident that both these different processes are characterized by the same equilibrium constants. Also the kinetics associated to direct chromium(VI) sequestration and two-step reduction-sorption are also thought to be different.
急求各位提出宝贵建议,最好是文献中直接有给模型的,谢谢各位!
