戊二醛为合成消毒药,因其杀菌防霉效果显著而被医院广泛应用。《中国医院制剂规范》规定,用容量法测定本消毒液含量,由于该法采用的是滴定液与反应生成的中间体作用,仅能间接反映含量,同时操作繁杂费时,所用试液较多,终点难以掌握。因此,笔者利用戊二醛结构中的二个醛基有紫外吸收这一特点,选用紫外分光光度法测定其含量。现具体介绍如下: Glutaraldehyde is a synthetic disinfectant, which is widely used in hospitals due to its sterilizing and anti-mold effect. “Chinese hospital preparation norms” provides that the volumetric method for the determination of the content of the disinfectant, as the method uses the titration solution and the reaction intermediates role, can only indirectly reflect the content, while complicated and time-consuming operation, the test solution used more, End point difficult to grasp. Therefore, the author uses glutaraldehyde structure of the two aldehyde groups have the characteristics of UV absorption, the choice of UV spectrophotometry determination of its content. Now specifically described as follows:
