摘要
通过实验测定了泥炭中腐殖酸的含量,研究了硝化处理腐殖酸的工艺.实验表明从泥炭中提取的腐殖酸的含量会随硫酸的浓度(2~4 mol/L)增大而增大,而把泥炭硝化再经碱溶解酸沉淀,与使用相同浓度的酸相比,腐殖酸的含量增加近5%.此实验为分离提取腐殖酸肥料提供了一些必备的基本的参考依据.
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.
