摘要
为了提高天然褐煤腐植酸的应用,采用了硫酸作为氧化剂来改性不同地方的褐煤腐植酸,研究改性后的腐植酸含量、抗硬水性能的变化,结果表明:改性后的褐煤腐植酸含量、抗硬水性能与对照组相比较均有不同程度的提高。其中表现最好的是黑龙江褐煤,腐植酸含量提高了3.2%,抗硬水能力达到14°。
In order to improve the application of humic acid in nature lignite,using sulfuric acid as an oxidizing agent to transnature the humic acid of lignite which were from different places,and studied the change of content and resisting hard water nature. Result suggested that content and rejecting hard water nature had the enhancement in various degree. The best performance is Hei Longjiang lignite,the humic acid content increased by 3. 2%,rejected hard water to 14°.
