两点电位滴定法测定维生素B_6的含量

Determination of VB_6 by the Two-point Potentiometric Titration

提出了用两点电位滴定法测定维生素Ｂ骨含量的新方法，只需记录两次终点附近的ＡｇＮＯ３标准溶液的体积和相应电极电位值，即可利用两点法公式计算出终点体积，从而确定维生素Ｂ６含量．

A new method for determining vitamin B6 with the two point potentiometric titration was established. This method only needs note down the indicating electrode potential two times nearby the end point and the corresponding titrant volumes AgNO3 standard solution. The end-point can be calculated hy the two-point formula.
