| 摘 要： | 在利用磷钼蓝分光光度法测磷的含量时，由于磷钼蓝颜色极不稳定，致使测定结果不准确。为此，在显色后的溶液中加硫脲使颜色的稳定时间延长，提高了测试结果的准确性。

| Abstract: | When using blue luminosity of phosphorus and molybdenum to determine the phosphorus content,the result is not accurate because the blue luminosity is very unstable.So the mixture of sulphur and carbamide is added after the solution appears colour,which makes the stable time of colour longer and the result more accurate. |
