It is a white solid that dissolves in water. It is almost non-hygroscopic and has good shelf-life. ==Production== The salt is prepared by the electrolytic oxidation of sodium hydrogen sulfate: :2 NaHSO4 → Na2S2O8 + H2 Oxidation is conducted at a platinum anode.〔Pietzsch, A.; Adolph, G. J. Chem. Technol. Biotechnol. 1911, 30, 85.〕 In this way about 165,000 tons were produced in 2005. The standard redox potential of sodium persulfate into hydrogen sulfate is 2.1 V, which is higher than that of hydrogen peroxide (1.8 V) but lower than ozone (2.2 V).〔Block, Philip A., Richard A. Brown, and David Robinson. "Novel activation technologies for sodium persulfate in situ chemical oxidation." Proceedings of the Fourth International Conference on the remediation of chlorinated and recalcitrant compounds. 2004.〕 The sulfate radical formed in situ has a standard electrode potential of 2.7 V. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sodium persulfate」の詳細全文を読む スポンサード リンク
