Currently, there is a serious water crisis in the world, which necessitates the purification of polluted water. Nowadays, new methods have been presented for the treatment of contaminated water. In the present study, single- and multi-walled nanotubes were used for adsorption of aspirin and atrazine pharmaceutical pollutions from waste water. In addition, various tests were performed at six levels to evaluate the parameters of effects of the initial concentration of solution, level of nano-absorbent, contact duration, temperature and pH on pharmaceutical pollutions of aspirin and atrazine in two single- and multi-walled carbon nanotubes. Moreover, results of each level of the test were separately shown on diagrams based on the concentration percentage. After the comparison of results, it was demonstrated that in the parameter of effect of the initial concentration of solution, the pharmaceutical pollution of atrazine had the highest adsorption percentage (94.03%) in the presence of multi-walled carbon nanotubes. In terms of the total adsorption percentage of aspirin and atrazine, the highest adsorption percentage was observed in the presence of multi-walled carbon nanotubes.
