Data are presented to indicate the recovery one can expect with different diffusion times in the microdiffusion procedure for the determination of cyanide using Conway cells. Using a predetermined recovery factor, a diffusion time of 10 min is recommended for emergency situations. In the use of the pyridine-barbituric acid reagent for color development, it was found that the reagents could be added as rapidly as is manually possible and that while the color complex begins to fade as soon as developed, the error after 4 to 10 min ranges from 3 to 9%.
数据表明，在使用康威池测定氰化物的微扩散程序中，不同扩散时间下预期的回收率情况。对于紧急情况，使用预先确定的回收率因子时，建议扩散时间为10分钟。在使用吡啶 - 巴比妥酸试剂进行显色时，发现试剂可以尽可能快地手动添加，并且虽然显色后颜色络合物立即开始褪色，但4至10分钟后的误差范围为3%至9%。
