There is an oxidation process in two determination methods of total N and total P, so the samples' liquation and oxidation processes can be done simultaneously, and the standard curve can be acquired simultaneously by confecting blended standard solution,

由于二者测定时都存在将含氮、含磷化合物转化为硝酸盐和下磷酸盐的氧化过程，因此本研究考虑将污泥样品消解和样品的氧化过程同时进行，标准曲线也可以通过配制混合标准溶液来同时测定，这使得总氮、总磷测定流程得以简化。
