Sažetak
The kinetics of dissolution of zeolite X in 2 m NaOH solutions, at 338, 343, 348, and 353 K, were studied by (i) measuring changes in the concentrations 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 changes in the 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 the model of growth and dissolution proposed by Davies and Jones, taking into account the chemical and structural characteristics of zeolite X.
