Background an Objectives: Natural organic matters because of production of disinfection by products such as trihalomethanes, which are often carcinogenic disinfection, are of particular importance. Carbon nanotubes due to large surface area, and many other applications, are effective adsorbents for the removal of natural organic matter. The present study aimed to investigate the removal of natural organic compounds from aqueous solution by single-walled carbon nanotubes and kinetics and equilibrium adsorption process. Methods: in present study, single wall carbon nanotubes used for removal of natural organic matters from aqueous solution. Different variables such as pH of zero point of charge, pH and different concentration of natural organic matters were investigated. Results: pH survey show that with decreasing pH adsorption capacity increased also pH of zero charge was 6.7. Adsorption capacity of single wall carbon nanotubes for initial concentration of natural organic matters of 10, 5 and 3 mg/L were 66.24, 40.63 and 29.77, respectively. Conclusion: Single-walled carbon nanotubes due to features such as high surface area have great potential for the removal of natural organic matter from aqueous solution
