摘要
The paper researches a range of problems related to the peculiarities of calcium oxalate crystallization in the presence of amino acids on the bases of thermodynamic calculations and experimental data. The regularities of phase formation in the system Ca2+-C2O42--H2O-amino acid in a widely variable interval of component concentrations and pH are theoretically researched. The influence of pH on the thermodynamic stability of crystalline compounds is considered. The kinetic parameters of crystallization are determined: the induction period, the rate constant, the order of crystals' growth, and the influence of amino acids on the kinetics of crystallization of calcium oxalate is established.
