Capture of nitrogen oxides with a fibre chemisorbent

Abstract

A system for cleaning nitrogen oxides from a gas—air mixture was proposed. The degree of sorption of nitrogen dioxide is determined by the rate of passage of the gas—air mixture through the filter and its concentration. Weakly basic VION AN-1 fibre treated with 3% sodium hydroxide solution was used as the chemisorbent. A hypothesis was advanced concerning the chemistry of capture of nitrogen dioxide by weakly basic VION AN-1 fibre treated with 3% sodium hydroxide solution.
