Abstract

The issue of environmental pollution is one of the most important concerns of human societies. Adsorption is one of the simple and inexpensive methods of environmental protection. Adsorption is the process of transferring materials from the fluid phase to the solid phase. Adsorption isotherms have the ability to describe the mechanisms between adsorbent and absorbed at constant temperature. In this paper, we have extracted the equations of different isotherms with new and simple methods. In this regard, we have proved the isotherms of Langmuir, Brunauer, Emmett and Teller (BET) and Anderson
