关於抗坏血酸含量测定的方法很多,大约能分为三类,即滴定法、光电比色法及来才提出的纸上色层分析定量法。本文目的在於观察中央卫生研究院营养学系所使2,6-二氯酚靛酚滴定法(以下简称法一),与电比色法(以下简称法二)及R·Stronecker,W.Heimann与F.Matt的纸层分析定量法(以下简称法三)的准确度,此外又对等的光电比色某些点上作了观察。
About ascorbic acid determination of the many ways, can be divided into three categories, namely, titration, photoelectric colorimetry and to come to the paper color chromatography quantitative method. The purpose of this article is to observe the 2,6-dichlorophenol-indophenol titration (hereinafter referred to as method 1) used by the Department of Nutrition, Central Institute of Health, and the electrochromic method (hereinafter referred to as method II) and R. Stronecker, W. Heimann And F. Matt paper layer analysis quantitative method (hereinafter referred to as the third method) accuracy, in addition to the equivalent photoelectric colorimetric observed at some point.
