The Study of Dynamic Releasing Sorbate from the Sorbent Using Mathematical Model

Releasing of sorbate from the sorbent is a very important process in the environment. The process involves many issues that affect the environmental problem such as leaching of toxic substances from hazardous waste. Furthermore, the regeneration of sorbent and the recovery of sorbate are directly involved with this process. This work developed the new mathematical model which can be applied to represent and to describe the dynamic behavior of the process. The experimental data for the releasing of vitamin E from the silica was chosen to test and to verify the model. The desorption rate constant of the model was quantified by both linear and nonlinear regression. The results show that the new developed model from this work is applicable to represent the actual data from the experiment and the new theoretical based model is quite simple but meaningful.
