- Аннотация: For each chalk sample, the induction period of the homogeneous nucleation of a supersaturated CaHCO3 solution, obtained by dissolving the samples at pCO2 = 1 atm, was measured in the process of balancing to atmospheric CO2 pressure. Crystallization ability of chalks was correlated with the content of polysaccharides and cyclic hydrocarbons. Using the vapor adsorption method, the effect of biopolymers (Alg and pAsp) adsorbed on calcite on free surface energy was studied. Adsorbed biopolymers reduce the effective free energy of the surface, and therefore, for high supersaturation, reduce the nucleation rate.
