A review on interaction of phenolic pollutant with other pollutants in the binary adsorption system

Abstract

Due to the drastic industrial development, it has become evident that various harmful chemicals are released into the environment. Industrial effluent comprises pollutants of varied nature such as organic pollutants, heavy metals, dyes, and other toxic chemicals. Phenolic and its derivative pollutants are such groups of organic compounds which are widely detected in domestic wastewater. The pollutant is also associated with many different industrial effluents, making it a heterogenous mixture. So, to abate this toxic waste many treatment methods have emerged. Adsorption is one such treatment methods which has become the best available methods to treat an effluent of this nature. However, during the process of adsorption mixture of contaminants involves complex interactions such as synergism, antagonism, non-interaction, and competition between the solute molecules for the adsorbent. In this review paper, we have tried to identify interactions in binary adsorption setup of organic pollutants (phenol and 2,4-dichlorophenol). The study also considers interaction factors present in 3 multicomponent isotherms and other factors which are mostly associated with binary system to arrive on to suitable interaction.
