METHOD FOR PREPARING CHEMOSORPTION MATERIAL Russian patent published in 2008 - IPC C08J5/20 D06M11/11 B01J20/32 D06M11/155 D06M11/28

Abstract RU 2322459 C1

FIELD: chemical technology.

SUBSTANCE: invention relates to technology for preparing chemosorption materials possessing high protective properties with respect to ammonia vapors that can be used for using in filtering protective devices. Method involves impregnation of nonwoven activated fabric made of hydrocellulose fibers in an aqueous solution containing zinc chloride and nickel chloride. Also, this solution contains 1,2,3-propanetriol (glycerol) as a modifying agent taken in the amount 0.5-1.0% of the total amount of the prepared solution.

EFFECT: improved preparing method.
