Sažetak
Kinetics of dissolution of zeolite A in 1 m and 2 m NaOH solutions, at 338, 343, 348, and 353 K, were studied by (i) measuring the change in concentration of Si and Al in the liquid phase, (ii) determining of the stage of polycondensation of silicate anions in the liquid phase, (iii) following the change in particulate characteristics of the suspended zeolite A, and (iv) phase analysis of the solid during the dissolution. The results obtained were analyzed and discussed in accordance with known theories of dissolution, taking into account the chemical and structural characteristics of zeolites.
