Received February 25, 2009 Abstract — An investigation of the adsorption of gaseous formaldehyde in mixtures with aqueous vapor from atmosphere using natural celite klinoptilotit is reported. Samples from different mining sites were characterized by structural and elemental analyses; the adsorption efficiency was studied by means of spectroscopy and derivatography methods of analysis. The strong dependence of preliminary thermal treatment on sorbent capacity was detected. DOI: 10.1134/S2070205110010132
