Khlopin's Law

a law of the distribution of microcomponents between the solid and liquid phases. Discovered in 1924 by V. G. Khlopin, the law states that if two substances are isomorphic and the concentration of one of them in a given system is small, then the distribution of the microcomponent between the crystalline phase and the solution at constant temperature and pressure is characterized by a constant value and is independent of the quantitative ratio of the phases. In accordance with Khlopin’s law, for example, the distribution of radioactive microcomponents occurs during their coprecipitation with an isomorphic carrier.
