摘要
用 0.2%、0.5%、1.0%浓度氢氧化钠溶液对不同产地来源的风化煤和褐煤进行抽提,检测游离腐植酸含量,验证氢氧化钠溶液浓度对煤中游离腐植酸含量测定的影响.结果表明,就风化煤而言,1.0%浓度氢氧化钠溶液作为抽提剂测定结果,基本上低于 0.2%和 0.5%浓度的结果;就褐煤而言,用不同浓度氢氧化钠溶液抽提测定结果相差不大.
Abstract
The weathered coal and lignite from different origins were extracted with 0.2%,0.5%and 1.0%NaOH solutions to detect the content of free humic acid and to verify the effects of NaOH solution concentration on the determination of free humic acid content in coal.The results showed that the results of 1.0%NaOH solution as the extraction agent were lower than those of 0.2%and 0.5%for weathered coal.The results of the extraction with different concentrations of NaOH solution were not different for lignite.
