对 KBr压片法、KCl压片法及萨特勒图谱采用的糊状法所绘制的三氯异氰尿酸的红外光谱图进行了分析、对照。同时将三氯异氰尿酸分别与 KBr,KCl研磨 ,以及三氯异氰尿酸纯品进行了可见 -紫外吸收光谱对照。实验发现 ,KCl压片法克服了溶剂的影响 ,更简单、直观体现了物质的精细结构 ,且与 KCl研磨后的三氯异氰尿酸的纯品图谱一致 ,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图较好的方法
The infrared spectra of trichloroisocyanuric acid, which were drawn by KBr tablet method, KCl tablet tablet method and paste method by the method of Atlas, were analyzed and compared. At the same time, trichloroisocyanuric acid and KBr, KCl grinding, respectively, and trichloroisocyanuric acid were visible - UV absorption spectrum control. The experiment found that KCl tablet method overcomes the influence of solvent, more simple and intuitively reflects the fine structure of the material, and with the pure product of TCI after trituration of KCl, indicating that the structure has not changed. Therefore, KCl tabletting method is the better way to draw the IR spectrum of trichloroisocyanuric acid
