摘要
建立了一种分析甲醛含量的新方法，并用此方法测定了分析纯甲醛的含量为３６００％，相对标准偏差为００９％。甲醛中所带杂质甲醇以及乙醇均不干扰测定，甲酸的干扰可以扣除。
An new analytical method of formaldehyde,hydrogen peroxide oxidizing acid-base titration,was established.Formaldehyde content of 36 00%(analysis purity) is determined,and its relative standard deviation is 0 09%。The determination is not disturbed by impurities such as methanol and ethanol,and the disturbance of formate acid can be eliminated.This method has some distinguishing features,such as easy to be operated,easy to grasp the terminal point and uses the less volume of agents.
