Abstract

Nitric acid up to 55 per cent strength is obtained by absorption of dilute nitrogen oxides in water absorbed in fibrous substances such as glass-wool or asbestos, or, if the strength does not exceed 50 per cent, cotton may be used. The acid may be expressed from the absorbent fibrous material, or the process may be made continuous by supplying a small stream of water to the fibrous material contained in a tower or chamber while the current of gas is passing, and drawing off the acid at the bottom.
