The Particle-Size Distribution Method for Studying the Crystallization of Calcium Oxalate in the Presence of Impurities

Abstract

The crystallization of CaC₂O₄ · H₂О from model solutions of a crystal-forming medium (human urine) has been studied by the dispersion method. It is shown that addition of amino acids to a model solution slows down the growth of CaC₂O₄ · H₂О crystals and affects the specific surface area and dispersivity of solid samples. The decelerating effect of amino acids increases with an increase in their concentration and depends on the amino acid structure.
