Obtaining of the Mg2+ form of the zeolite 4A with ion exchange of magnesium salts

Abstract

Zeolites are sodium alumino silicates which in in their composition contain zeolite water. They have a three-dimensional structure. Spatial structure defined by a strictly defined geometry of pores and cavities. For ionic еchange is used magnesium salt (MgCl 2 *6H 2 O) whose aqueous solutions were with the following concentrations (MgCl 2 *6H 2 O) = 2,5; 3.5; 4,5 mol / dm 3 , and other parameters of the ion exchange: time t = 20, 30, 40 and temperature of 298 and 330 K. Ionian capacity is calculated as mmgMgO / 1g zeolite.
