摘要
碱法草浆造纸废水在酸性条件下经乙醚萃取———K_D浓缩器浓缩 ,采用气相色谱_质谱 (GC_MS)联用仪对其有机污染物进行了分析研究。结果表明 ,该废水中共含有 2 9种有机物 ,其中主要为有机酸类 ,占有机物总量的 5 0 84%。其次为难降解的呋喃类和毒性较大的苯环类有机物 ,它们分别占有机物总量的 2 5 1 2 %和 1 3 5 3 %。
In this paper, the extraction of organic compounds in alkali straw pulp papermaking wastewater with diethyl ether was conducted in acidic condition. Extracted phase after concentrated with Kuderna_Danish (K_D) concentrator was analyzed by GC_MS.29 kinds organic compounds were identified, and it was found that the major organic compounds were organic acids,furans and benzenes with concentrations of 50.84%,25.12% and 13.53%, respectively.
