Title: Study on Treatment Process of Humic Acid with Nitrifying Method
Abstract: From the experiment,the contents of humic acid contained in sapropelic coal were determined,and the technology of nitrifying humic acid was studied.The experiment results showed that the content of humic acid increased with raising the concentration of sulfuric acid(2~4 mol/L).In the same condition,when the sapropelic coal was nitrified,the content of humic acid increased by 5%.This paper provided some necessary basic reference data for separating and extracting humic acid fertilizers.
