三氯异氰尿酸红外光谱测绘方法探讨

Study on Determination Method of Trichloro S Trlazinc 2,4,6 (1H,3H,5H) Trion by IR Spectrometry

本文对ＫＢｒ压片法、ＫＣｌ压片法以及萨特勒图谱采用的，糊剂法所绘制的三氯异氰尿酸的红外光谱进行了分析、对照。ＫＣｌ压片法克服了溶剂的影响，简单、直观地体现了物质的精细结构。同时，将三氯异氰尿酸分别与ＫＣｌ、ＫＢｒ研磨，和三氯异氰尿酸纯品进行了紫外－可见吸收光谱对照。实验发现，与ＫＢｒ研磨的三氯异氰尿酸和纯品的吸收峰有差异，而与ＫＣｌ研磨后的三氯异氰尿酸和纯品一致，说明结构未发生变化。因此，认为ＫＣｌ压片法是绘制三氯异氰尿酸红外光谱较好的方法。

The paper made acompanision among IR absorption spectra of thrichloro s trlazine 2,4,6(1H,3H,5H) trion which were gotten by KBr,KCl wafer and mull technique,which was used in Sadtler Infrared Spectroscopy Atlats.It was found that KCl wafer eliminated the effect of solvent and directly demonstrated the fine structure of material.The UV VIS absorption spectrum of trichloro s trlazine 2,4,6(1H,3H,5H) trion grinded in KCl was the same with the pure sample,so material had not changed.The IR spectrum of trichloro s trlazine 2,4,6 (1H,3H,5H) trion was satisfactory through KCl wafer.
