Description
<使用試薬>
溶液A:3M酢酸緩衝液(pH5.2)
溶液B:0.25%CyDTAおよび20mMスルホベンジルトリジン
<スルホベンジルトリジン>
ナトリウム塩型の構造式を以下に示す。なお、前述の通り、本発明にはカリウム塩も使用することができる。
<分光光度計>
株式会社日立製作所製 U−2000Aを使用した。
上記水溶液を100mg/Lに希釈して測定用水溶液とした。この測定用水溶液5mLに対して上記溶液A(60μL)および溶液B(30μL)をこの順序で添加した後、30℃の恒温槽中で正確に5分間反応を行った。この反応後の溶液に対して分光光度計を用いて675nmの吸光度を測定した。得られた吸光度から図3に示した検量線を使用して測定用の水溶液の過硫酸ナトリウム濃度を求め、希釈倍率(10倍)を考慮して988mg/Lの測定値を得た。
JIS K 8253の「ペルオキソ二硫酸カリウム」の6.1に従い、上記水溶液につき濃度測定を行った。
DPD法により上記水溶液につき濃度測定を行った。
