I have no prior experience in Langmuir and Freundlich isotherm model utilization in data anlysis. Kindly, If anyone could explain from the basic I will be extremely grateful.

Nihal Shahriyar hopes this article help you. This study was done by me to evaluate the removal of methylene blue by the silica-based adsorbent.
In your case, the only difference is you have to measure time-dependent concentration data by using AAS. To plot isotherms you have to work with 5 different starting concentrations with the same weight of adsorbent. However, I recommended you to first optimize kinetic parameters
The principle is to generate partitioning data usually by a batch process. You need to make graded additions and measure what is left in solution. The models themselves are clear sailing, but there is a serious (unresolved) statistical problem in the fitting.
