Abstract

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
