摘要
研究了硝酸浓度、氧化时间及煤酸比对提高风化煤中腐植酸含量的影响。结果表明，当煤酸比为０．４、硝酸浓度为３３％、氧化时间３０ｍｉｎ时，风化煤的腐植酸含量可由２９．５％提高到６１．４％
The influence of nitric acid content, oxidation time and coal to nitric acid ratio was studied on the increasing content of humic acid. The result showed that under the condition of coal to nitric acid ratio 0.4, nitric acid content 33% and oxidation time 30min, the content of humic acid in efflorescent coal can be increased form 29.5% to 61.4%.
