Synthesis and physicochemical properties of NaK, K, Na, and Li forms of LSX zeolite

Powder LSX zeolite samples of high phase purity and near 100% crystallinity have been synthesized in NaK, K, Na, and Li forms. The effect of the chemical nature and content of the exchange cation and air calcination temperature on the degree of crystallinity and the porous structure characteristics and adsorption properties of the mentioned LSX zeolite forms were established by X-ray diffraction and adsorption methods.
