| 摘 要： | 该文采用吡啶—巴比妥酸分光光度法对水样中的总氰化物进行测定,探讨了氰化物测定的各预处理体系,选用了9种预处理体系分别对八种金属氰络合物进行了实验研究,并使金属氰络合物与游离氰含量比为1:1的条件下考察其游离情况.实验表明,除3种预处理体系外,其它预处理体系均获得了满意的结果.

| Abstract: | The method for the total cyanide determination in water samples by pyridine - barbitone acid spec-trophotometry is applied. Nine pretreatment systems for the total cyanide determination were reseached in their effects on the dissociation efficiency of eight metal cyanide complexes. The results indicated that six pretreatment systems of all were applied to be the pretreatment systems for the total cyanide determination and satisfactory results were obtained. |
