Abstract
This study demonstrated the feasibility of using zirconium dioxide nanoparticles (ZrO2 NPs) synthesixed
using a hydrothermal technique for the removal of lead in aqueous solution. The physico-chemical
characterization illustrated that the synthesized ZrO2 NPs have a non-uniform shape with an average
size of 15 nm, surface area of 41.56 m2 g-1 and adsorption pore width of 3.06 nm. These findings
revealed the potential use of ZrO2 NPs for chelating lead ions. The maximum lead adsorption capacity
of ZrO2 NPs was obtained around 4.12 mg g-1 at adsorption conditions i.e., stirring speed of 200 rpm
and contact time of 120 min. Thus, this method provides a number of advantages, including an efficient
and cost-effective method for the removal of lead using ZrO2 NPs.
