摘　　要：为解决氯苯、二甲苯沸点高、试剂难驱除的缺点、本文选用低沸点试剂二氯甲烷进行超声波脱色30min,60℃常压蒸馏12min来完全驱除二氯甲烷,通过样品测试表明二氯甲烷脱色方法优于GB/T 23344-2009《纺织品4-氨基偶氮苯的测定》附录A的脱色方法。In order to solve Chlorobenzene,xylene in high boiling point,difficult to dispel the disadvantages of rea-gents.This paper uses low boiling reagent dichloromethane for ultrasonic decolorization 30min,12min at 60 C can com-pletely dispel dichloromethane.Through sample test,dichloromethane decolorization is superior to GB/T23344-2009” Textiles-Determination of 4-aminoazobenzene” by appendix A decolorization method.
