摘要
利用分光光度法比较不同活性条件下活性炭的脱色能力，同时利用测折光率的方法测量氧化铝、弗罗里夕吸附油的效率。这两种方法可以方便地检查出农药残留分析中净化剂的性能。
We have compared the decolorizing efficiency of activated char under different conditions by using spectrophotometry, and have also determined the efficiency of absorbing oil of Al 2O 3 and frolise by measuring refractivity .The two simple methods can be employed to check the performance of depurant uesed in the analysis of residual pesticide.
