    Factors Affecting the Leaching of Lead from UPVC Pipes

    Results showed that, for a given UPVC pipe, the rate of leaching of lead depended primarily on temperature and the nature of extractants. While the rate of leaching of lead was quite low with distilled water, it was very much enhanced by the presence of low concentration of anions such as C1-, HPO 4 2- HCO 3 - , NO 3 - , SO 4 2- and EDTA.
