Removal Elements from an Industrial Wastewater of Refinery at Different Temperatures using CNTs

H. I. Abdulgafour, F. M. Mohammed, M. A. Abdul-Majeed

Abstract: This study describes the adsorption capability and treatment efficiency of Al-Dora refinery wastewater treatment unit using multiwall carbon nanotubes (MWCNTs). A divalent heavy metal ions (cobalt, lead, copper), oil content, total suspended solids (TSS), nitrate oxides (NO3, NO2), chemical oxygen demand (COD) and trihalomethanes (THMs) were selected as a field case study in this research. The adsorption characteristics of elements on the adsorption behaviour towards MWCNTs from wastewater of Al- Dora refinery at different temperatures (25, 3o, 40, 50, 60, 70 oC) were studied. The higher adsorption capacity was found to be around 110.1 mg g1 for oil and THMs at 50 C. For heavy metals removal cobalt was found higher percentage removal compared to other ions (lead and copper) which is about 60 %, while the percentage removal of COD, nitrate and TSS was 97 %, 83 % and 73 %, respectively. This research approved the high efficiency and unique properties of the carbon-based nanomaterials as promising industrial wastewater treatment technology.
