  abstract: Water resources are being polluted from various sources. Types of emerging pollutants are also increasing while the traditional pollutants are not solved efficiently yet. Removal of toxic metals is one of the biggest challenges in ensuring safe water for all. Those can be removed by chemical processes, physical processes such as ultra filtration and reverse osmosis, adsorption by polymers and various types of media which exhaust fast and expensive to reactivate. Cadmium (Cd2+) was selected, in the present study, for its potential hazards to living beings at low concentration and difficulties in removing from water. Therefore, due to their high adsorption capacity and high surface area, carbon nanotubes (CNT) were synthesized and used to remove cadmium from water. Fixed catalyst chemical vapor deposition reactor (FCCVD) system was fabricated, upgraded and used to grow carbon nanotubes. Growth parameters (reaction time, reaction temperature, and gas flow rates) for CNT on powdered activated carbon (PAC), as a novel substrate were optimized. The PAC was impregnated with Fe3+ catalyst. Design Expert software was used to design the experimental plan and to determine the optimization parameters for the growth of CNT, considering removal (%) of Cd2+ as a response. Based on the screening test, four samples were selected for detailed study. Selected CNT-PAC samples were characterized using field emission electron microscope (FESEM) and transmission electron microscope (TEM) to confirm the CNT growth as well as to study the microstructure of the nanoscale product. In addition, the selected CNT-PAC samples were further characterized using Fourier transform spectroscopy (FTIR), thermal gravimetric analysis (TGA) and Brunauer, Emmett and Teller (BET) surface area. The surface properties of CNT-PAC were modified by oxidative functionalization using three different methods: sonication with KMnO4, refluxing with HNO3 at 140 oC and in-situ gasification with CO2 at 750 oC.
