Abstract
The desorption of cations from crystalline polysilicates and polysilicic acids, A and Y zeolites, and natural mordenite in the NH4, H, and dealuminized forms under the action of a strong electrostatic field at temperatures ranging from 20 to 600°C has been studied. The desorption of sodium and potassium cations was detected above a temperature of 150–200°C, and magnesium, calcium, and aluminum cations were not detected. Potassium cations are desorbed at lower temperatures than are sodium cations. Zeolite NaA retains cations more strongly than-does zeolite NaY. The observed spectra are consistent with the concentrations of the cations and the structural features of the samples studied.
