ABSTRACT:
NO.sub.x is absorbed in an alkaline aqueous solution of a permanganate and/or a manganate and the manganese compounds are reduced to form the precipitate of manganese dioxide.
The manganese dioxide is dispersed in an aqueous solution of sodium or potassium hydroxide having a concentration of higher than 20% and a gas containing NO.sub.x having a molar ratio of NO.sub.2 /NO.sub.x of higher than 0.55 is contacted with the dispersion in the presence of a permanganate and/or a manganate at higher than 40.degree. C, to convert manganese dioxide to the permanganate and/or the manganate.
