FTIR-ATR法快速鉴定T-PVC

Rapid Identification of Thermoplastic Elastomer of Polyv inyl Chloride by Attenuated Total Reflection Infrared Spectrography

以环己酮为溶剂 ,无水乙醇为沉淀剂 ,溶解 -沉淀法消除增塑剂的干扰 ,以锗晶体为反射晶体 ,衰减全反射红外光谱法定性测定聚氯乙烯成分。该法简单、快速、安全、准确。

The dissolvation-precipitation technique with cyclobexanone as dissolvent and a lcohol absolute as the precipitator was used to remove the interference of plast icizer,and FTIR-ATR technique was used to qualitatively analyze polyvinyl chlor ide with germanium as ATR crystal material.The method is simple and rapid with s atisfactory results.
