The shortage and extremely high utilization of water resources and the necessity of water with optimal quality for drinking and agricultural use and the preservation of the environment, human has led to the purification of industrial waste and wastewater by preventing the entrance of pollutants into surface water and underground water and creating a trusted cycle. One of the most dangerous pollutants that threating human health and the environment is Pharmaceutical pollution. Due to the high solubility of drugs, conventional purification cannot completely eliminate these contaminants, and the researchers have noted the use of new techniques such as the use of nanotechnology in water treatment, which entails high initial costs. For this reason, one has to look for a solution to these costs; one of the most commonly used methods of using theoretical methods.Â In this study, an effective method for treating carbon nanotubes in artificial nanotubes using the artificial neural network (ANN) system and the fuzzy-nerve adaptive inference system (ANFIS) has been used. Some structural descriptors Such as polar surface area, LUMO, HOMO and molecular volume were calculated and studied for more influential performance in experimental experiments.Â In this regard, the control error and the test error were analyzed and the correlation between the effective parameters was determined. Then, a parameter that has a greater impact on water contamination has been identified in the presence and absence of carbon nanotubes. As a result, the polar surface has the greatest impact.

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. Manuscript profile

The water scarcity crisis and water pollution are among the key issues both in the current century and in the future. Several different techniques have been introduced for the decontamination of water pollution, among which using the nanotubes is one of the most influential. In this project, the single-walled and multi-walled carbon nanotubeswere employed to test the possibility of removing heavy metal ions, such as Fe2+, Cd2+, Pb2+ and Ni2+. The effects of three factors including carbon nanotubes, ions’ initial concentration, and contact time were tested. According to the difference rate of nanotubes’ adsorption diagrams, the maximum differences in the performance of single- and multi-walled are obtained as 30 percent for the initial solution concentration and around 5 percent for Nano adsorbent concentration. The results showed that in the different initial concentrations of metal ions, multi-walled nanotube had a better performance, while in case of changing the amount of adsorbent; the single-walled nanotube had a higher adsorption. And if the time changes, multi-walled carbon nanotube can have a higher adsorption. Manuscript profile
