摘　　要：本文分别采用过硫酸钾消解-钼酸铵分光光度法和连续流动-钼酸铵分光光度法对废水样品中的总磷进行测定。结果表明,两种分析方法测定值的相对偏差为-13.00%~2.00%,对于86.7%的废水样品来说,两种方法结果的相对偏差保持在10%以内。利用CFA1100测定总磷时,结果准确可靠,分析速度快,人们可以将其应用于大批量的总磷废水监测工作中。In this paper,the total phosphorus in wastewater samples was determined by potassium persulfate digestionammonium molybdate spectrophotometry and continuous flow-ammonium molybdate spectrophotometry.The results show that the relative deviation of the measured values of the two analysis methods is -13.00% to 2.00%.For 86.7% of the wastewater samples,the relative deviation of the results of the two methods is kept within 10%.When using CFA1100 to determine the total phosphorus,the results are accurate and reliable,and the analysis speed is fast,people can apply it to the monitoring work of large-scale total phosphorus wastewater.
