乙醛含量测定方法的改进

IMPROVING THE METHOD FOR DETERMINING THE ACETALDEHYDE CONTENT

乙醛含量测定方法一般有盐酸羟胺法和亚硫酸氢钠加成法，这两种方法都存在某些问题，测定结果偏差很大，本文主要是对亚硫酸氢钠加成法进行探讨与改进，使其测定手续更简便，测定结果的精密度大大提高。

Commonly used methods for determining the acetaldehyde content of a solution include thehydroxylamine method and the NaHSO_3 addition method. Both of these methods have someproblems,and the result obtained often contains a high degree of error. Thepresent paperlcoksinto the NaHSO_3 addition method and proposes ways of improving it,so that the procedureissimplified and the result attains a much higher precision.
