GDX101树脂小吸附柱富集水中有机污染物

CONCENTRATNG ORGANIC POLLUTANTS IN POTABLE WATER WITH THE SMALL ABSORPTENT COLUMN PACKED GDX-101 RESIN

用国产高分子多孔小球树脂GDX101装填为i.d.4mm×50mm的小吸附柱,在高温下通高纯氮气净化,可以获得较低的树脂本底,能满足水中痕量有机物分析的要求。用小吸附柱富集水中痕量有机污染物,经少量二氯甲烷洗脱,以气相色谱测定。方法对于多环芳烃、邻苯二甲酸酯、农药等有较好的回收率。

Using the small absorptent column with 4mm, i.d.x 50mm length packed by GDX-101 resin and purifying through nitrogen gas at 350℃. Has been applied to concentrate trace orginic pollutants in potable water, Self-basis of the absorptent column is low and the recoveries of the method for PAH, ester phthalate and pesticide are more than 75%.
