Abstract

The object of this work was to determine the solubility and stability of the synthetic Ca₅(As_x- P_{1－xO₄)₃F solid solution at 25 ℃ and different pHs by batch dissolution experiments. The results indicated that the solubility and stability of Ca₅(As_xP_{1－xO₄)₃F in aqueous solution were strongly dependent on the solution pH. During the dissolution, the dissolved arsenic concentration under acidic condition was ten times higher than that under neutral-alkaline condition. Based on the analytical result at 25 ℃ and pH 6, the solubility product (K_sp) and the free energy of formation (ΔG_f⁰) for the Ca₅(As_xP_{1－xO₄)₃F solid solution were calculated, which increased with the increasing mole fraction of P and As in the solid solution.}}}

Key words: arsenic, fluorapatite, solid solution, solubility
