【摘要】 采用ＵＦ膜法，使用国产超滤膜对华东地区４ 种主要地表天然原水，进行了有机物分子量分布的测定。结果表明４ 种地表天然原水中，分子量小于４ ０００ 的溶解性有机物占５０ ％ 以上更多还原

【Abstract】 In this paper, the molecular distributions of dissolved organic matter were determined by UF method using homemade UF membrane for 4 water samples of raw surface water in East China area. The results show that dissolved organic compounds with molecular weight smaller than 4 000 Daltons account for more than 50 percent.更多还原
