水中总磷测定校准曲线制作探讨

Comparison of Experimental Parameters between Standard Curve and Working Curve of Determination of Total P in Water

对过硫酸钾消解 -钼蓝比色法测定水中总磷的标准曲线和标准工作曲线进行了实验比较 ,两者在空白试验、重现性试验和空白加标回收试验等方面均无显著性差异。

The comparison of experiment parameters were conducted between standard curve and working curve of determination of total P in water.And there were no differences between two groups(P>0.05 in all experiment parameters).
