摘要
本文以弱酸在水中的电离平衡理论为依据,研究了采用气相色谱测定工业乙酸钠的方法。通过讨论样品酸化,萃取处理过程中的酸度、萃取剂、时间、温度及电离常数对分析结果的影响,得到了最佳的分析方案,获得了满意的结果,从而对乙酸钠的测定可以GC方法代替容量法。
According to the theory of the weak acid dissociative equilibrium in the water, the paper researches the method that industry natrium etha-noic acid is determined by GC. It discusses the effect of the acidness、the time, the temperature in the progress of dealing with the sample and dissociation content on the result to get the best program of the analysis. The result is satisfactory. so the analysis of capacity can be replaced by Gc for detcrming natrium ethanoic acid
