摘要
利用一系列XAD吸附树脂及大孔阴、阳离子交换树脂,将太湖水中溶解态有机物分离为溶解态富里酸类、腐殖酸类、憎水弱酸类、憎水碱类、憎水中性物类、亲水酸类、亲水碱类七种组分,分别对不同组分的有机物进行氯化处理后,用GC/MS选择离子峰面积法测定了产物中的MX[3-氯-4-(二氯甲基)-5-羟基-2(5H)-呋喃酮]。结果表明,太湖水体中的溶解态腐殖酸类可能是生成MX的重要前驱物。
Dissolved organic matter from Taihu lake water was isolated and fractionated into seven fractions of fulvic acids, humic acids , hydrophobic weak acids , hydrophobic neutrals, hydrophobic bases, hydrophilic acids, hydrophilic bases by sorbtion on a series of resin absorbents. After chlorine treatment of the fractions MX [3-chloro-4-(dichloromethyl)-5-hydroxy-2 (5H)-furanone] was determined with GC/MS in the selected ion monitoring mode. Results suggest that the fulvic acids might be the most important precursor.
