摘  要:
分别采用过氧化氢、硝酸、硫酸作为氧化剂氧化改性风化煤,研究改性后风化煤的腐植酸含量及由其提取得到的腐植酸钾抗硬水性能变化。结果表明:改性后风化煤的腐植酸含量与未经氧化处理的风化煤相比有不同程度的提高;提取得到的腐植酸钾的E_4/E_6值、凝聚限度及官能团含量也有所提高,抗硬水性能得到改善。改性效果最好的氧化剂是硝酸,其次是硫酸、过氧化氢。

摘  要:
Hydrogen peroxide, nitric acid, sulfuric acid are used as oxidants to modify humic acid in weatheredcoal,the change of humic acid content in weathered coal and resistance to hard water of potassium humateobtained from extraction are studied. The results suggest that the humic acid content enhances in variousdegree;the value of E_4/E_6,condensing limit,functional groups content of potassium humate are increased,itsresistance to hard water is improved. The best modifying agent is nitric acid, followed by sulfuric acid andhydrogen peroxide.
