摘　　要：用连续流动分析仪与异烟酸-吡唑啉酮分光光度法对水中总氰化物进行了测定,并对两种方法的测定值进行了比较,结果显示连续流动分析仪的准确度、精密度较异烟酸-吡唑啉酮分光光度法好,吡唑啉酮分光光度法在分析时需要时间较长。The total cyanide in water was determined by continuous flow analyzer and isonicotinic acid pyrazolone spectrophotometry,and the measured values of the two methods were compared. The results showed that the accuracy and precision of continuous flow analyzer were better than isonicotinic acid pyrazolone spectrophotometry,and the analysis time of pyrazolone spectrophotometry was longer.
