Analysis of sodium hydroxide in polyformaldehyde
Thread Content
Want to test whether polyformaldehyde contains NaOH? There is no good analysis method; please give some advice.
It’s not entirely clear; the suggestions are as follows: 1. Measure the pH value to determine whether OH anions are present. 2. Use flame qualitative analysis to detect sodium ions. However, the best approach is to derive it from the manufacturing process, taking into account the raw materials used and the mechanism of the reaction, and then calculate the remaining substances through process analysis. Sorry for the inconvenience
The usual method is to measure the ash content and detect the sodium ion level in the depolymerization solution
