以十七烷酸为内标试剂,用甲基叔丁基醚对水样进行液-液萃取后,用三甲基氯代硅烷和N-O-双-(三甲基硅烷基)三氟乙酰胺进行硅烷化处理,以吡啶为溶剂,用GC-MS仪对造纸厂二次纤维造纸车间的污水样进行定性和相对含量分析,检出约50种有机污染物.主要是植物原料的小分子溶出物、树脂酸、脂肪酸及各种化学添加剂.树脂酸在制浆污水中的含量较大,主要来自造纸原料和松香施胶剂;脂肪酸、芳香酸及其衍生物主要存在于澄清白水和混合污水中,主要来源于二次纤维浆、造纸原料与各种添加剂;相对而言,最终进入污水处理厂前的混合污水中有机物质种类最多;真空泵密封水中有机污染物的种类最少,主要是难降解性的芳香类化合物.讨论了不同生产工段污水中各种有机污染物质的差异和来源及对环境的危害性.
