<正> 催化动力学法测定痕量CN~-具有较高的灵敏度。方法大致可分为两类:一类是利用CN~-对某些反应的催化加速作用,另一类是利用CN~-对某些催化反应的阻抑作用。文献[1]对CN催化加速对—硝基苯甲醛与邻—二硝基苯反应作了不少研究,但对这两种试剂的纯度要求很高。本文利用普通纯
In this paper, we have studied the conditions of determining tracecyanide with the reaction of p--nitrobezaldehyde and o--dinitrobenzene. Using benzyl alcohol as a inhibitor. By this method can be used todetermine trace cyanids in various water samples.
