Description
蒸留水に次亜塩素酸ナトリウム(和光純薬工業株式会社製)を溶解し、濃度が60mgCl2/Lの次亜塩素酸ナトリウム水溶液を調製した。また、蒸留水に臭化ナトリウム(汎アジア貿易株式会社製)を溶解し、濃度が12,880mg/L(臭化物イオン(Br-)換算濃度として10,000mg/L)の臭化ナトリウム水溶液を調製した。
蒸留水に替えて水道水(愛媛県松山市の水道水)を用い、実験例1と同様に操作して紫外線吸収スペクトルを測定した。結果を表2および図2に示す。表2に記載の濃度は計算値である。
表1および表2に示した次亜塩素酸ナトリウムの極大吸収波長(290nm)の吸光度と次亜塩素酸ナトリウム濃度(mgCl2/L)との対応関係をプロットし、次亜塩素酸ナトリウム水溶液における次亜塩素酸ナトリウムの定量用の検量線を作成した。また、表1および表2に示した次亜臭素酸ナトリウムの極大吸光波長(330nm)の吸光度と次亜臭素酸ナトリウム濃度(mgBr2/L)との対応関係をプロットし、次亜塩素酸ナトリウム水溶液における次亜臭素酸ナトリウムの定量用の検量線を作成した。これらの検量線を図3に示す。
表1および表2に示した吸光度比Xと次亜塩素酸ナトリウム濃度(mgCl2/L)との対応関係をプロットし、次亜塩素酸ナトリウム水溶液における次亜塩素酸ナトリウムの定量用の検量線を作成した。また、表1および表2に示した吸光度比Yと次亜臭素酸ナトリウム濃度(mgBr2/L)との対応関係をプロットし、次亜塩素酸ナトリウム水溶液における次亜臭素酸ナトリウムの定量用の検量線を作成した。これらの検量線を図4に示す。
