| 摘 要： | 利用 2种不同方法从云南中甸沼泽土中提取的腐殖酸 ,对亚甲蓝溶液进行了吸附性能研究。结果表明 :腐殖酸对亚甲基蓝的吸附受到振荡时间、温度等影响 ,与pH的关系不大 ,腐殖酸对亚甲基蓝的吸附符合朗格谬尔吸附理论 ,为单分子层吸附。 2种方法提取的腐殖酸吸附规律基本一致 ,但由于焦磷酸钠法提取的腐殖酸具有较大的比表面积 ,因而它的吸附能力更强

| Abstract: | The adsorptive property of methylene blue by humic acid which was extracted by two different methods from swampy soil in Zhongdian of Yunnan was studied.The results shows that the humic acid is effective to adsorb methylene blue.The adsorptive properties from aqueous solutions are influenced by time and temperature.The adsorption is in accord with Langmuir adsorption theory.The two humic acids have the simliar rule,but the humic acid by sodium pyrophosphate has better adsorption because of its bigger specific surface area. |
