Abstract :

Population growth, industrial development and technology transfer are among the factors of increasing water consumption and waste water production in communities and environmental pollution. Today, this pollution has become a big problem, which has made it necessary to invest in water treatment. Heavy metals are one of the most problematic and dangerous pollutants for the environment and humans. Mercury is considered as a global pollutant and a very toxic element due to its accumulation effect and high persistence in the environment. To remove toxic metals, the adsorbents that are easy and fast to separate and do not cause secondary pollution are preferred. In this study, a modified magnetic carbon nanotube has been prepared and used to remove mercury from polluted water. The physical, chemical and morphological characteristics of the adsorbent were determined with FT-IR and FESEM analyses. In the optimal conditions of pH=6, ambient temperature, 0.1 g of adsorbent, concentration of 10 ppm and time of 60 minutes, the adsorption efficiency was 96%.
