(57) [Problem] To provide a capturing method capable of easily and efficiently extracting even a trace amount of a dissolved water-soluble organic compound. SOLUTION: In the formula, M is a hydrogen atom, a metal, ammonium, lower alkylammonium, lower alkanolamine or pyridine, and X is S, S O or SO 2 , and n is an integer of 4 to 6. The phenol sulfide sulfonic acid derivative represented by the formula (2) is used as a water-soluble organic compound scavenger, and is brought into contact with an aqueous solution containing a water-soluble organic compound. |
