PROBLEM TO BE SOLVED: To provide a method for analyzing oxalic acids in an organic solution, capable of recognizing the oxalic acids in the organic solution.SOLUTION: The oxalic acid analysis method includes a pre-treatment step of bringing an organic solution insoluble to water into contact with water, and an analysis step of analyzing the solution obtained in the pre-treatment step, the steps being performed in this order. In the method, the oxalic acids can be detected in the organic solution, which enables recognition of whether the oxalic acids are present in the organic solution. The method also enables an analysis sample to be prepared only by bringing the hydrophobic organic solution into contact with water. Thus, it is possible to extremely simplify the analysis step and speedily obtain an analysis result.SELECTED DRAWING: Figure 1 |
