The adsorption is one of the technologies most used in the removal of contaminants from water and has been gaining prominence. In the treatment of effluents, activated carbon adsorption (AC) is an efficient method. The main advantage of CA production is the use of waste that would often be discarded inappropriately. The purpose of this article is to organize some available information regarding the potential coal of activated carbon as bioadsorbent. Periodic research was carried out on the production of activated carbon with adsorptive characteristics, in the removal of contaminants in wastewater. The effectiveness of this technique under different parameters influences the adsorption process, such as: pH of the solution, initial concentration of the dye, contact time, amount of adsorbent and temperature. The adsorption isotherms of Langmuir, Freundlich and BET models (Brunauer, Emmett and Teller) are generally used to evaluate the adsorption capacity of bioadsorants. In all the articles studied charcoal characteristics as bioadsorbents have shown to be promising in the process of removal of waste water pollutants. It is concluded that the adsorption isotherms of Langmuir, Freundlich and BET are often used to evaluate the adsorption capacity of the activated carbon.
