摘要
本实验用自行研制的简易气提－浓缩装置，与气相色谱仪联用，在适当的实验条件下，对造纸污冷凝水中微量低沸点挥发醇的混合物进行了有效的测定。检测下限为～１０μｇ／Ｌ，变异系数＜１０％，加标回收率＞８１％。
A simplified strip-concentration apparatus could be connected with GC was developed successfully in our lab. Under suitable conditions,it could be used to analyse the trace amount of volatile alcoholates in the contaninated condensates of pulping mills.The detection limits are lowing to 1 to 10μg/L, the standard deviations are lower than 0.01 and the recoveries are higher than 81%.
