Photocatalyst treatment for lead(II) using titanium oxide nanoparticles embedded in PVA-alginate beads

In this paper, titanium oxide nanoparticles were produced using the hydrothermal method and embedded in PVA–alginate beads to remove Pb(II) ions from aqueous solutions. The kinetics of the photocatalyst process was elucidated by varying operating parameters such as pH (3, 7 and 10) and initial Pb(II...
