摘　　要：为准备检测电磁屏蔽纺织品中芳香胺残留量,进一步明确旋转蒸发仪的浓缩压强、柠檬酸盐缓冲溶液的pH值以及水浴锅振摇与否3个前处理参数并进行优化。实验结果表明,旋转蒸发仪的压强为300mbar时各类芳香胺的回收率及实验效率最高,在水浴振摇及柠檬酸盐缓冲溶液pH值为5.5～6.1的条件下处理样品得到的检测结果更理想。In order to determine the residual aromatic compounds in electromagnetic shielding textiles,the followed pretreatment parameters should be clear and optimized:the pressure of rotary vacuum evaporator,water-bath vibration shake and the pH value of buffer solution.It is found that,when the pressure of rotary vacuum evaporator is 300 mbar,highest recovery of the aromatic amines and experiment efficiency will be gained.The investigation also points out that with waterbath vibration shaking and the pH value of buffer solution between 5.5 and 6.1,relatively ideal detection results can be got.
