| 摘 要： | 研究了不同浓度的各种无机酸对褐煤中腐殖酸含量、CEC及其光学性质变化规律的影响。试验结果表明:H_3PO_4和HCl处理能在一定程度上提高阳离子交换能力,但对腐殖酸含量及光学性质基本无影响。一定强度的HNO_3能使腐殖酸含量增加25％以上,阳离子交换能力有了很大程度提高,且随硝酸强度的变化过程要明显滞后于腐殖酸含量的变化过程,光学性质发生了很大变化。不同褐煤达到最佳处理效果的条件也不尽相同。

| Abstract: | The effects of various kinds of inorganic acids on the content,cation exchange capacity and optics natureof humic acid in brown coal were studied. The content and the optics nature were not affected by phosphoric acidand hydrochloric acid treatment,but can be increased the exchange capacity to some extent. The content of humicacid can be increased by 25 per by suitable for intensity nitric acid, The cation exchange capacity can be greatly in-creased and the optics characteristic was greatly changed. The best condition would be different to different browncoal. |

| Keywords: | humic acid brown coal cation exchange capacity E_4/E_5 |
