摘要：

The influence of the preexposure of various nanoporous aluminosilicate sorbents to a pulse magnetic field on the adsorption of the formaldehyde vapor was considered. The effect of the pulse magnetic field on the surface morphology of the sorbents and intensifying the sorption activity was estimated. A magnetic field with B = 0.011 T intensified the adsorption by a montmorillonite sample, while an increase in the magnetic induction from 0.011 to 0.12 T enhanced the adsorption by clinoptilolite-containing samples. A combination of the pulse magnetic field (B = 0.011 T) and thermal treatment intensified the adsorption of formaldehyde at all the sorbents studied. The sorbents exposed to the pulse magnetic field were most active 48 h after the exposure. The relaxation time was 72 h for all the systems studied at different B values.
