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。
In this paper, IR spectra of trichloroisocyanuric acid drawn by KBr tabletting method, KCl tabletting method and Sadler ’s mapping method were analyzed and compared. KCl tablet method to overcome the impact of solvents, simple and intuitive to reflect the fine structure of the material. At the same time, trichloroisocyanuric acid and KCl, KBr grinding, respectively, and trichloroisocyanuric acid were pure UV-Vis absorption spectrophotometry. The experimental results show that there is a difference between the absorption peak of trichloroisocyanuric acid and pure KBr-milled products, which is consistent with that of trichloroisocyanuric acid and pure product of KCl after milling, indicating that the structure has not changed. Therefore, KCl tabletting method is considered to be a better method for the IR spectrum of trichloroisocyanuric acid.
