PROBLEM TO BE SOLVED: To provide a decomposition treatment method for hydrogen peroxide in seawater.SOLUTION: In one or a plurality of embodiments, a decomposition treatment method for hydrogen peroxide in seawater includes adding a reductant to seawater comprising hydrogen peroxide of 5-650 mg/L so that the concentration becomes a level obtained by increasing an equimolar equivalent of the hydrogen peroxide by 0.1-10 mmol/L. The reductant is a compound that generates sulfite ions.COPYRIGHT: (C)2015,JPO&INPIT【課題】海水中の過酸化水素の分解処理方法の提供。【解決手段】一又は複数の実施形態において、海水中に含まれる過酸化水素を分解処理する方法であって、5~650mg/Lの過酸化水素を含む海水に、前記過酸化水素の等モル当量に0.1~10mmol/Lを上乗せした濃度となるように還元剤を添加することを含み、前記還元剤が、亜硫酸イオンを生成する化合物である、過酸化水素の分解処理方法。【選択図】なし
