摘　　要：以云南各产地褐煤为原料制备硝基腐植酸,对褐煤水分、灰分、总腐植酸、游离腐植酸进行了分析和评价。给出了各种原料煤腐植酸中总酸性基、羧基、酚羟基的分析数据。采用云南罗茨褐煤进行催化氧化,由氧化褐煤制备硝基腐植酸,对制备工艺进行了考察,并对产品质量进行分析。试验结果对腐植酸资源和硝基腐植酸生产工艺的选择利用具有指导意义。In this paper, the resources of brown coal produced nitro-humic acid from different regions in Yunnan province were investigated. The content of moisture, ash, total humic acid and free humic acid of brown coal were analyzed, and the data of total acidic group, carboxy and phenolic hydroxyl group were given. The extraction process producing nitro-humic acid by oxidizing brown coal obtained from Luoci was selected, and the production quality was analyzed. The results could direct proper use of humic acid resources and selection of process producing nitro-humic acid.
