Determination of the optimal conditions for obtaining potassium nitro-humate from lignite
Raw lignite is enriched by humic acids by oxidation with nitric acid. The optimal conditions for producing potassium nitro-humate were defined by investigating the level of neutralization of the oxidized lignite, by means of potassium hydroxide. The increased content of humic acids and potassium in...
