Abstract: The leaching of lead from unplasticized poly(vinyl chloride) pipes under different temperatures and by different extractants was studied. The extractants used were tap water, sodium hydrogen carbonate and disodium hydrogen phosphate solutions. The results show that for tap water and sodium hydrogen carbonate extractants, increasing the temperature generally increases the leaching rate of lead. The reverse was observed for the phosphate extractant. The study also shows that the extrusion temperature of the pipes affects the leaching rate of lead by water. Less lead is leached from pipes extruded at higher temperature. © 1988.
