| 摘 要： | 采用衰减全反射(ATR)-傅里叶变换红外光谱(FTIR)法测试丁腈橡胶(NBR)的结合丙烯腈含量,并以燃烧法测得的结合丙烯腈含量为标准值,绘制FTIR谱特征峰吸光度比值与NBR中结合丙烯腈含量的标准工作曲线。结果表明,FTIR谱中波数为2 240和1 440 cm~(-1)处的特征峰的吸光度比值(A_(2240)/A_(1440))与NBR中结合丙烯腈含量具有很好的线性关系,根据FTIR谱的A_(2240)/A_(1440)可以计算得到NBR中结合丙烯腈含量。ATR-FTIR法操作简单快捷,测试结果与燃烧法测试结果的误差不大于1.3%,准确度高。

| Abstract: | Infrared attenuated total reflection(ATR) method in this article was used to determinate the acrylonitrile content in nitrile rubber. The standard values of acrylonitrile content were confirmed by combustion method to draw the standard curve of infrared absorbance ratio and acrylonitrile content, through which the calculation method was get. the method has the advantages of simple operation and fast measurement, Compared to combustion method, the error of experimental was below 1.3%. |
