| 摘 要： | 通过钼锑抗分光光度法测定总磷的精密度偏性试验及其结果分析,提出本标准方法用光程10mm比色皿比色测定时,由于测定的灵敏度较低,使总磷低浓度测定的精密度和准确度难于达到标准方法要求;建议钼锑抗分光光度法测定总磷时,最好选用30mm比色皿比色测定.

| Abstract: | The experiment of determining precision bias of total P in molybdenum-antimony anti-spectrophotometric method indicates that, when determining with detector of 10mm optical path, the precision and accuracy for TP low-concentration determination can hardly meet the requirement, due to the low determination sensitivity. Detector of 30mm optical path is suggested to use when determining TP in molybdenum-antimony anti-spectrophotometric method. |
