What is What is the solubility of zeolite A? about?
A meaningful solubility product of a zeolite should remain constant as composition of zeolite mother liquors varies at a given temperature. We identify a solubility product of zeolite A, H s = [Si(OH)4][AI(OHn][Na +] = 1.2 x 10 -s M 3, from experimental data in highly alkaline aqueous solutions under conditions typical for zeolite A synthesis (1 M\_<[Na]<4 M, 353 K< T<363 K). To accomplish this we develop a thermodynamic model of dilute sodium aluminosilicate solutions representing mother liquors in equilibrium with zeolite A. Proper modeling of the liquid phase adjacent to a growing zeolite is necessary to obtain meaningful supersaturation values and solubility products. Further quantitative modeling of solution mediated zeolite growth and dissolution should include a physically relevant model of aluminosilicate speciation in the liquid phase.
