Abstract
The aims of the study is to prepare a functionalized multiwall carbon nanotube and use it for the removal of Malathion pesticides from polluted water, the synthesized multiwall carbon nanotube exhibits an excellent chemical, and thermal stability, the analyses were done using a High Performance Liquid Chromatography (HPLC) to measure the remaining amount of substances in the solution after the adsorption process, the obtained results showed that the efficiency for the removals of Malathion were noticeable rose when using a functionalized MWCNT, unfortunately it's decreased to about the half amount (52.74%) with presence of Dissolved Organic Matter, indicating that nonselective adsorbent toward malathion.
However, it took no more than 50 minutes to remove high levels of the dissolved amount depending on the starting laboratory conditions and adsorbent uses, at the optimum removal conditions, the percentage reach (98.34%) of the target pollutant at initial concentration of 6 ppm with neutral pH. Regenerated in three cases showing a little decrease in the adsorbent efficiency, so it can be reusable and efficient materials for removal of malathion pesticide, and use it as specialized filters to capture malathion from polluted groundwater
