In order to solve the problems of low detection efficiency of phosphate in boiler water and cooling water of nuclear power plant, the automation operation has not been realized, and the operation risk of radioactive samples is high, a flow injection method for the determination of phosphate was investigated. The method is based on the reaction of phosphate with molybdate and metavanadate to form yellow phosphovanadium molybdic acid complex in acid medium, and the detection is carried out at the wavelength of 420 nm. The results show that the method exhibits good linearity in the phosphate mass concentration range of 0-500 mg/L (correlation coefficient R=0.999), with a method detection limit of 2.28 mg/L. The relative standard deviations at low, medium, and high concentration levels are 2.41%, 1.61%, and 1.33%, respectively. Compared with the conventional spectrophotometric method, the relative error ranges from -0.81% to 1.27%. This method meets the requirements for phosphate determination in nuclear power plant boiler feed water and cooling water. The method enables fully automated sample analysis, with an analysis cycle of only 100 seconds per sample, significantly improving detection efficiency and automation level while greatly reducing the risk of radioactive exposure to operators. It provides an efficient, accurate, and safe automated analytical technique for rapid and precise phosphate detection in the field of nuclear power chemistry, demonstrating important engineering application value.

针对核电厂锅炉用水与冷却水中磷酸盐检测效率低、自动化程度不足及放射性样品操作风险高等技术难题,研究了采用流动注射法测定其中的磷酸盐浓度。该方法基于酸性介质中磷酸盐与偏钒酸盐、钼酸盐生成黄色磷钒钼酸络合物的反应,在420 nm波长下进行检测。结果表明:磷酸盐质量浓度在0~500 mg/L范围内线性良好(相关系数R=0.999),方法检出限为2.28 mg/L;低、中、高3个浓度水平的相对标准偏差(RSD)分别为2.41%、1.61%、1.33%,与传统分光光度法比较,相对误差仅在-0.81%~1.27%范围内,可满足核电厂锅炉用水与冷却水中磷酸盐检测要求。该方法实现了样品检测的全自动化,单个样品分析周期仅100 s,可显著提高磷酸盐的检测效率和自动化水平,大大降低操作人员的放射性暴露风险,为核电化学领域磷酸盐的快速精准检测提供了一种高效、准确、安全的自动化分析技术,具有重要的工程应用价值。

针对核电厂锅炉用水与冷却水中磷酸盐检测效率低、自动化程度不足及放射性样品操作风险高等技术难题,研究了采用流动注射法测定其中的磷酸盐浓度。该方法基于酸性介质中磷酸盐与偏钒酸盐、钼酸盐生成黄色磷钒钼酸络合物的反应,在420 nm波长下进行检测。结果表明:磷酸盐质量浓度在0~500 mg/L范围内线性良好(相关系数R=0.999),方法检出限为2.28 mg/L;低、中、高3个浓度水平的相对标准偏差(RSD)分别为2.41%、1.61%、1.33%,与传统分光光度法比较,相对误差仅在-0.81%~1.27%范围内,可满足核电厂锅炉用水与冷却水中磷酸盐检测要求。该方法实现了样品检测的全自动化,单个样品分析周期仅100 s,可显著提高磷酸盐的检测效率和自动化水平,大大降低操作人员的放射性暴露风险,为核电化学领域磷酸盐的快速精准检测提供了一种高效、准确、安全的自动化分析技术,具有重要的工程应用价值。

In order to solve the problems of low detection efficiency of phosphate in boiler water and cooling water of nuclear power plant, the automation operation has not been realized, and the operation risk of radioactive samples is high, a flow injection method for the determination of phosphate was investigated. The method is based on the reaction of phosphate with molybdate and metavanadate to form yellow phosphovanadium molybdic acid complex in acid medium, and the detection is carried out at the wavelength of 420 nm. The results show that the method exhibits good linearity in the phosphate mass concentration range of 0-500 mg/L (correlation coefficient R=0.999), with a method detection limit of 2.28 mg/L. The relative standard deviations at low, medium, and high concentration levels are 2.41%, 1.61%, and 1.33%, respectively. Compared with the conventional spectrophotometric method, the relative error ranges from -0.81% to 1.27%. This method meets the requirements for phosphate determination in nuclear power plant boiler feed water and cooling water. The method enables fully automated sample analysis, with an analysis cycle of only 100 seconds per sample, significantly improving detection efficiency and automation level while greatly reducing the risk of radioactive exposure to operators. It provides an efficient, accurate, and safe automated analytical technique for rapid and precise phosphate detection in the field of nuclear power chemistry, demonstrating important engineering application value.
