摘要
采用燃烧氧化—红外线分析法在线测定了水中的总有机碳,结果显示:总有机碳水质在线设备基本性能指标重复性为0.5%、零点漂移0%、量程漂移-2.21%,在与实验室比对监测结果表明:比对实验测试范围-17.5%~1.58%之间,合格率达85.3%,结果符合技术规范要求。可见总有机碳水质燃烧氧化—红外线分析法在线监测方法可以连续、较准确地监测水质变化并实现远程监控,为水质预警、环保监管服务。
The total organic carbon in water was determined online by combustion oxidation-infrared analysis method. The results show that the repeatability of basic performance indicators of the online equipment is 0.5%; zero drift is 0%; range drift is-2.21%. Compared with laboratory monitoring results, the qualified rate is 85.3%, which meets the technical specifications. The on-line monitoring method of total organic carbon water quality combustion oxidation-infrared analysis can continuously and accurately monitor water quality changes and realize remote monitoring, serving for water quality early warning and environmental protection supervision.
