Kinetic characteristics of the crystallization from model solutions of blood plasma

Resumo

The kinetic regularities of crystallization (growth order and constants) in a model solution of blood plasma have been investigated. The particular order and crystallization constant are determined to be n < 1 and k = 12.30–26.91 molⁿ L^–n s^–n, respectively. The impurities are found to form the following descending sequence with respect to their inf luence on the particular kinetic characteristics of crystallization: milky acid > magnesium ions > alanine, glycine, glucose, and citric acid. It is shown that the impurities affect to a greater extent the nucleation rather than the growth stage. It is also established that a change in рН within 7.0–8.0 does not affect the crystallization parameters of the system modeling the composition of human blood plasma.
