摘要
传统的水中硫化物、氰化物分析方法具有以下特点:实验过程要操作迅速,对操作人员手速要求较高;测试时间长,从取样到分析出结果需几个小时的时间;手工方法的操作过程中,样品与环境有较多接触,测定结果受环境干扰。QUAATRO型连续流动注射仪采用全自动分析,减少了人为操作可能造成的误差,提高了分析速度,且减少了环境干扰情况的发生。本研究探讨连续流动注射仪测定水中硫化物和氰化物的应用。
The traditional analysis methods of sulfide and cyanide in water have the following characteristics:the experimental process needs to be operated quickly and requires high manual speed of the operator;the test time is long,and it takes several hours from sampling to analyzing the results;manual method during the operation process,the sample has more contact with the environment,and the measurement result is interfered by the environment.The QUAATRO continuous flow injection instrument adopts fully automatic analysis,which reduces the error that may be caused by human operation,improves the analysis speed,and reduces the occurrence of environmental interference.This study explores the application of continuous flow injection instrument in the determination of sulfide and cyanide in water.
