The work presents some results of our investigation of chemisorption-catalytic behavior o f natural bentonite (N-Bent) based compositions containing copper(II) or iron(III) chloride or both these salts in the process o f air purification from sulfur dioxide. Both N-Bent and the compositions were characterized by X-ray phase analysis, FT-IR spectroscopy, DTG-DTA, water vapor ad/desorption, pH-metry and also tested in the reaction with sulfur dioxide contained in the air.otherdioxideenvironmental impuritiesairsulfur dioxideArticle
