摘　　要：地表水中总磷含量是水质评价中的重要指标之一。应用流动注射分析法测定昆明学院洋浦校区地表水中的总磷含量。该方法在总磷质量浓度0.050~1.60 mg/L范围与峰高响应值呈良好线性关系(r=0.9993),检出限为0.007 mg/L,用于测定水样中总磷含量,相对标准偏差在0.27%~3.61%之间,加标回收率97%~117%。实验结果与“GB11893-89钼酸铵分光光度法”比较,无显著差异,简便、快速、准确,可用于批量样品分析。Total phosphorus content in surface water is one of the important indicators of water quality evaluation.The flow injection analyzer was used for the determination of total phosphorus in surface water of Yangpu Campus of Kunming University.Linear relationship between values of Peak height and mass concentration of total phosphorus was obtained 0.050-1.60 mg/L(r=0.9993),with values of limit of 0.007 mg/L.This proposed method was supplied to the determination of total phosphorus in water samples with relative standard deviation in the range of 0.27%~3.61%.The recover rate of standard of addition is 97%~117%.Compared with method of ammonium molybdate spectrophotography in GB11893-89,the result had not significant difference.Test result shows that the method is simple,fast accurate and applicable to determine total phosphorus in water.It is suitable for largescale sample analysis.
