通过试验对常见的自来水厂消毒剂分析仪进行了对比,包括实验室仪表和在线仪表,找出了适合复合二氧化氯消毒工艺中采用的检测仪器和测试方法,并论证了其适用性。研究表明,基于甘氨酸掩蔽-DPD比色法的实验室二氧化氯分析方法,电极法二氧化氯在线分析仪,以及基于DPD显色分析的在线余氯分析仪,均可以在该体系中得以应用。 Through experiments, we compared the common disinfectant analyzers in waterworks, including laboratory instruments and on-line instruments, and found the suitable instrumentation and testing methods for the compound chlorine dioxide disinfection process. Studies have shown that the laboratory chlorine dioxide assay based on glycine-masked-DPD colorimetric method, the electrode chlorine dioxide on-line analyzer, and the on-line chlorine analyzer based on DPD colorimetric analysis can be applied in this system .
