By means of ,strong, oxidability of potassium permanganate, water-insoluble NO can be oxidized into NO2 so sa to be absorbed with SO2 at the same time in later period. When potassium permanganate exists and Ca/(S+0.5N) is 1.8, calcium-based sorbent can be used to obtain desulfurization rate of 31.4% and denitration rate of 13.5%.

One means of reducing the ,acidity, of phosphonic acid is to neutralize it with an alkali salt; typically potassium hydroxide (KOH). The resulting solution contains mono-and di-potassium salts of phosphorous acid (often referred to as potassium phosphite), and is the active ingredient in Alude, Magellan, Vital, Vital Sign, Resyst, and other phosphonate fungicides.
