摘　　要：文章通过对分光光度法和SKALAR SAN++连续流动分析仪对测定水中氰化物做了比较和实验。结果表明,连续流动分析仪分析水中挥发酚与分光光度法相当,两种方法测定水中的挥发酚均具有较高的准确度和精密度,能满足环境国家标准的要求,而连续流动分析仪器实现了分析全过程的自动化,同时分析股成长避免了使用三氯甲烷对分析人员身体的危害,更能满足目前环境监测分析定时、大量的特点。Based on the spectrophotometric method with the Holland SKALAR SAN＋＋ continuous flow analyzer for the determination of water of cyanide in doing a comparison and experiment. The results showed that two kinds of analysis method in accuracy, stability and recovery can reach the determination requirements, and there was no significant difference between them.
