The IR spectroscopy and complex thermal analysis have been used to analyze the adsorption capacity of Transcarpathian clinoptilolite, both naturally occurring and activated, relative to water vapor. Activation of clinoptilolite with an H2SO4 25%-solution was found to cause dealumination and the appearance of additional adsorption centers, allow for the maximum ability to adsorb water vapor. Activation with a 5% solution of HCl at the 1:10 solid-liquid ratio ensures the significant dealumination of the mineral with no breakdown of its structure and the occurrence of transient pores and macropores in this mineral. Because of such activation clinoptilolite is far more able to absorb molecules of the green dye.
