摘要
对山东龙口的洼里褐煤、北皂长焰煤进行了稀硝酸氧化降解制备硝基腐植酸的实验研究，获得了影响硝基腐植酸产率的诸因素，如硝酸浓度、氧解温度、氧解时间、煤粒度等的影响规律。对氧解产物硝基腐植酸进行了ＦＴ－ＩＲ，光密度Ｅ＿４／Ｅ＿６以及主要活性基团的测定，论述了煤硝酸氧化降解的化学反应模式。
The experimental investigation of Shangdong Longkou low rank coal oxidized with diluent nitric acid solution in order to prepare nitrohumic acid (NHAm) carried out in labratory.The effects of HNO3 concentration,oxidization temperature,oxidization duration,coal granular size on the yield of NHAm obtained are studied.FT-IR the ratio of optical extinction E_4/E_6 and the major active chemical radicals in NHAm are determined to the oxidized product NHAm.The chemical reaction model of coal oxidized with HNO_3 solution is reviewed also.
