Humic acid (HA ) was abstracted from leonardite,and a composite superabsorbent (HA PSA ) was prepared by compounding poly (acrylic acid ) and lignitic humic acid. 以风化褐煤为原料制备腐植酸(HA),将HA与普通型保水剂(PSA)复合,获得HA型保水剂(HA-PSA)。
The results indicated that the trace elements molybdenum and zirconium increased considerably the gas yields of the lignitic organic matter while selenium did not. 分析结果表明,除硒元素外,随着钼元素和锆元素的加入,褐煤有机质气态产物的生成量显著提高。
