Studies have shown that CNTs possess great potential for removing heavy metal ions such as Cd 2+, Cu 2+, Ni 2+, Pb 2+, Zn 2+, etc. The adsorption of heavy metal ions from solution on CNTs has been proven mainly due to the surface functional groups on CNTs, and it.

metal concentrations and pH were low, whereas for Ni and Pb the removal efficiency was highest at high pH and concentrations of metals in aqueous solution. The results summarized that O. westti are suitable to remove selected heavy metals from the aqueous solution and can be used in the treatment of wastewater (WW).
