| Abstract: | Application fuchsin sulfite solution and formaldehyde at room temperature and acidic conditions to form blue-violet compounds of this principle, quantitative colorimetric, determination of formaldehyde content. This method with the commonly used acetylacetone spectrophotometric comparison, the results of the two methods are basically the same. And this method is simple, without heating, non-toxic, etc. |
