摘要：
A system for treating waste gas in which the waste gas is contacted with an absorbent which contains manganese dioxide; thereafter contacting the absorbent with water to solubilize salts of manganese with an acidic ion exchange resin that retains manganese and passes acids formed from manganese salts; contacting the ion exchange resin and contained manganese with dilute nitric acid to obtain Mn(NO.sub.3).sub.2 solution; and precipitating MnO.sub.2 from the Mn(NO.sub.3).sub.2 solution.
