总磷自动监测仪与钼酸盐分光光度方法的比较
|
摘要
指出了总磷自动监测仪与传统的钼酸铵分光光度法相比,对标准样品以及各种水质的水样总磷的测定结果无明显差异,精密度和准确度均能达到国家标准要求。但总磷在线自动监测技术的运行,可以极大地提高水质总磷监测水平和质量。
This paper compares the determination of total phosphorus with automatic monitor and laboratory method of Ammonium molybdate spectrophotometry between standard samples and surface water. The results show thatmonitoring results of automatic monitor also have good accuracy and precision, which can satisfy the requirements of national standards.The operation of on-line automatic monitoring technology of total phosphorus can greatly improve the monitoring level and quality of total phosphorus of water.
