| Abstract: | 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. |
