Nanotechnology has many applications in a number of industries; one of the most important applications is to modify clay that absorbs impurities in water. During the experiment, temperature and pressure remain constant. Effect of three factors such as PH corresponds to the reaction which takes place, and the amount of the sorbent and the absorbance mixing time of aromatic substances which is listed by modified clay nanoparticles in aqueous solutions have been investigated. The test results reveal that a shift from acidic to an alkaline medium bring about the amount of aromatic material absorbed by modified clay. In addition, an increase in the weight of absorbent material also increases the absorption of aromatic materials. By changing the mixing time at different pH levels, it observed that increasing the mixing time for a certain period would increase the number of aromatics absorbed, and then the amount of adsorption would be fixed; hence, there is an optimal time to mix the adsorbent substance with the industrial wastes.
