Impact of orthophosphate on the solubility and properties of lead orthophosphate nanoparticles.

ABSTRACT: Orthophosphate (PO₄) is a commonly used corrosion control treatment to reduce lead (Pb) concentrations in drinking water. PO₄ reduces Pb concentrations by forming relatively insoluble lead phosphate (Pb-PO₄) minerals. In some cases, however, Pb-PO₄ minerals have been observed to form nanoparticles, and if suspended in water, these nanoparticles can be mobile and reach consumer taps. Although recent research on Pb-PO₄ particles has been performed, there remains a need to improve our understanding of the nature of Pb-PO₄ nanoparticles. For that reason, Pb precipitation experiments were conducted to generate Pb-PO₄ nanoparticles in bench scale studies for analysis. The study objective was to observe how pH, dissolved
