摘要: 利用选择性萃取分离技术对不同淡水中培养的生物膜主要化学组分(铁氧化物、 锰 氧化物和有机质)进行选择性萃取分离, 通过比较其萃取效率, 讨论了选择性萃取分离技 术的适用性.

关键词: 自然水体, 生物膜, 铁、锰氧化物, 有机质, 选择性萃取

Abstract: The separation of chemical components of freshwater surface coatings, developed in different natural waters, was carried out by means of selective e xtraction technique, and the results obtained were compared and the serviceabi lity of the selective extraction technique was discussed by comparing the extrac tion efficiencies.

Key words: natural water, surface coatings, iron and manganese oxides, or ganic material, selective extraction
