Abstract
【解決手段】臭素酸イオンとの共存によって蛍光強度が変化する蛍光物質を試料水に添加し、塩酸添加により酸性条件とする第1工程と、蛍光物質の蛍光強度を計測する第2工程と、臭素酸イオンを含まない標準試料水の蛍光強度と計測された蛍光強度との差を蛍光強度差として算出する第3工程と、予め求めた蛍光強度差と臭素酸イオン濃度との検量線を用いて、算出された蛍光強度差から臭素酸イオン濃度を算出する第4工程とを含む臭素酸イオンの測定方法において、第2工程が、励起波長及び蛍光波長がそれぞれ264nm及び400nmである時、励起波長及び蛍光波長がそれぞれ264nm及び480nmである時、及び励起波長及び蛍光波長がそれぞれ300nm及び400nmである時のうちのいずれかの時の蛍光強度を計測する工程を含む。
【選択図】図1
Description
本発明の発明者らは、鋭意研究を重ねてきた結果、励起波長及び蛍光波長がそれぞれ300nm及び480nmである時以外にもTFPの蛍光強度が変化することを発見した。具体的には、図1(a),(b)はそれぞれ、臭素酸イオン濃度が0μg/L及び20μg/Lである試料水にTFP溶液(294μM)を添加し、塩酸添加により酸性条件とした時のTFPの励起蛍光スペクトルを示す図である。励起蛍光スペクトルは、株式会社島津製作所製の分光蛍光光度計RF−5300PC及び日立ハイテクノロジーズ株式会社製の分光蛍光光度計F−2700を用いて測定した。
次に、本発明の発明者らは、励起波長及び蛍光波長がそれぞれ264nm及び400nmである時及び励起波長及び蛍光波長がそれぞれ300nm及び480nmである時の最適塩酸濃度を評価した。図3(a),(b)はそれぞれ、励起波長及び蛍光波長がそれぞれ264nm及び400nmである時及び励起波長及び蛍光波長がそれぞれ300nm及び480nmである時の、塩酸濃度(HCl)の変化に伴う臭素酸イオン濃度が0μg/Lの時の蛍光強度(F.I.)及び臭素酸イオン濃度が0μg/Lである時の蛍光強度と臭素酸イオン濃度が20μg/Lである時の蛍光強度との蛍光強度差の絶対値(ΔF.I.)の変化を示す図である。
本発明の発明者らは、励起波長及び蛍光波長をそれぞれ264nm及び400nmとした時の蛍光強度に対する硝酸イオンの影響を評価した。図6(a),(b)はそれぞれ、励起波長及び蛍光波長がそれぞれ264nm及び400nmである時及び励起波長及び蛍光波長がそれぞれ300nm及び480nmである時の、硝酸イオン濃度(NO3 −)の変化に伴う臭素酸イオン濃度が0μg/Lの時の蛍光強度(F.I.)及び臭素酸イオン濃度が0μg/Lである時の蛍光強度と臭素酸イオン濃度が20μg/Lである時の蛍光強度との蛍光強度差の絶対値(ΔF.I.)の変化を示す図である。図6(b)に示すように、従来の測定波長である励起波長及び蛍光波長がそれぞれ300nm及び480nmである時には、硝酸イオン濃度の変化に伴う蛍光強度のばらつきが大きく、また強度変化の傾きも変動するために、臭素酸イオン濃度を正確に算出することが困難であった。一方、図6(a)に示すように、新たに確認されたピーク波長である励起波長及び蛍光波長がそれぞれ264nm及び400nmである時には、硝酸イオン濃度の変化に伴う蛍光強度のばらつきが小さく、傾きも変動しないため、臭素酸イオン濃度を正確に算出することができた。このことから、励起波長及び蛍光波長をそれぞれ264nm及び400nmとすることによって、硝酸イオンの影響を受けずに臭素酸イオン濃度を精度高く測定できることが知見された。なお、図示しないが、励起波長及び蛍光波長がそれぞれ300nm及び400nmである時にも同様に、硝酸イオンの影響を受けずに臭素酸イオン濃度を精度高く測定できることが確認された。
原水に対しオゾン処理を行う際、原水に遊離塩素が含まれている場合には、遊離塩素が蛍光強度の測定精度に影響を及ぼす。また、原水に遊離塩素が含まれている場合、オゾン処理によって塩素酸イオン(ClO3 −)が生成する。そこで、本発明の発明者らは、臭素酸イオン濃度0μg/Lの溶液について、各ピーク波長における塩素酸イオンの濃度変化に対する蛍光強度の変化を測定した。図7は、各ピーク波長における塩素酸イオンの濃度変化に対する臭素酸イオン濃度が0μg/Lの時の蛍光強度(F.I.)の変化を示す図である。図7に示すように、各ピーク波長における蛍光強度は塩素酸イオンの濃度が変化しても大きく変化しなかった。このことから、塩素酸イオンは蛍光強度を正確に測定する上では妨害物質とはならないことを確認できた。
