Abstract:
Interaction of Pb2+ and H2PO4- ions in acetate buffer solutions results in the formation of a precipitate with variable composition Pb-x(PO4)(y)A(z), where A(-) is a monovalent anion. In the presence of excess chloride (the Cl-: H2PO4- molar ratios from 0.5 to 2.0) in the range 4.10 <= pH <= 4.95, the precipitate composition is approximately formulated as Pb5Cl(PO4)(3) (Pb : P = 1.667). In the absence of chlorides, the Pb2+ : H2PO4- ratio decreases to 1.56-1.62 during precipitation.
