Water contamination caused by rapid economic and industrial development, along with population growth, poses a serious threat to public health worldwide. Heavy metals, being important environmental contaminants, have significant impacts on human, animal, and plant health. This study introduces a new adsorbent material for heavy metal removal, showing promising results in adsorption efficiency.
Rapid economic and industrial development and population growth have made water contamination a serious environmental problem and a major threat to public health worldwide. Heavy metals are extensively used in numerous industrial applications and are some of the most important environmental contaminants. The impacts of heavy metals on the health of humans, animals, and plants make their removal from wastewater and water resources an important and vital issue. In this study, a simple and environmentally friendly method is proposed for the synthesis of a ZnFe2O4-carbon nanotube (CNT) adsorbent material. SEM/EDX analysis and Fourier-transform infrared spectrophotometry (FTIR) are used to characterize the synthesized adsorbent material. We test the synthesized adsorbent material's ability to recover four heavy metals (Hg(II), Pb(II), Cd(II) and Sn(II) ions) from an aqueous solution. We show that crushing fullerene CNTs with the ZnFe2O4 composite improves the adsorption properties of free fullerene CNTs towards the investigated heavy metal ions by 25%.
