光电指示终点微库仑法测定食用油的酸值

Determination of the acid value of edible oil using Photoelectric indicaling the end point micro-Coulomb method

提出了一种光电指示终点的微库仑法测定食用油酸值的方法。该法不需要制备和标定滴定剂、操作筒便、快速、精密度高、而且节约大量溶剂,可以为地沟检测提供借鉴。

This paper proposes a photoelectric indicating the end point micro coulometric determination of acid value of edible oil. The method does not require preparation and calibration of titrant, the operating cylinder, fast, high precision, but also save large amounts of solvent, and worth promoting.
