A process and device for enhancing the chemical protection capability of a collective protection filter whereby the process stream exiting the collective protection filter is passed through an Auxiliary Filter. The auxiliary filter containing an ammonia removal media, such as zirconium hydroxide impregnated with zinc chloride (ZnCl/Zr(OH)), an oxidizing media, preferably zirconium hydroxide impregnated with potassium permanganate (KMnO/Zr(OH)), and a methyl bromide removal media, preferably activated carbon impregnated with triethylenediamine (TEDA/carbon). The auxiliary filter and process are configured to remove toxic industrial chemicals including NH, NO(mixtures of NO and NO) and CHO, and CHBr.

Auxiliary filter for enhanced chemical protection

The present invention relates to a textile composite for the adsorption and breakdown of harmful chemical materials. A support layer and a sorptive and reactive material mounted on the support layer form a protective layer, which is mounted on an inner liner. The protective layer adsorbs and breaks down harmful chemical materials. An outer shell is formed of fabric having an outer surface that is hydrophobic for resisting the passage of harmful chemicals, which may be in the form of vapor, liquid or aerosols. Preferably, the sorptive and reactive material includes zirconium hydroxide, and the support layer includes a fabric material. The zirconium hydroxide is distributed on the fabric material in the amount of at least 20 grams of zirconium hydroxide per square meter. Alternatively, the zirconium hydroxide is distributed in the amount of at least 150 or 200 grams of zirconium hydroxide per square meter.
