Title (EN) FUNCTIONAL WATER CONCENTRATION SENSOR, AND CALCULATION METHOD
(FR) CAPTEUR DE CONCENTRATION D'EAU FONCTIONNELLE ET PROCÉDÉ DE CALCUL
(JA) 機能水濃度センサ、及び、算出方法
Abstract:
(EN) A functional water concentration sensor (1) comprises: a light source (10) for emitting ultraviolet light (11); a container (20) into which functional water (90) having a pH of 6-9 inclusive is introduced, the functional water (90) containing hypochlorous acid and hypochlorite ions separated from the hypochlorous acid; a light-receiving element (30); and a signal-processing unit (40). The signal-processing unit (40) calculates the concentration of hypochlorite ions in the functional water (90) on the basis of an output signal, calculates the ratio of the hypochlorous acid and the hypochlorite ions in the functional water (90) on the basis of the pH of the functional water (90) and a separation constant pKa of the hypochlorous acid, and calculates the concentration of hypochlorous acid in the functional water (90) on the basis of the calculated concentration of hypochlorite ions and the calculated ratio.
(FR) La présente invention concerne un capteur de concentration d’eau fonctionnelle (1) qui comprend : une source de lumière (10) pour émettre une lumière ultraviolette (11) ; un récipient (20) dans lequel de l’eau fonctionnelle (90) ayant un pH de 6 à 9 inclus est introduite, l’eau fonctionnelle (90) contenant de l’acide hypochloreux et des ions hypochlorite séparés de l’acide hypochloreux ; un élément de réception de lumière (30) ; et une unité de traitement de signal (40). L’unité de traitement de signal (40) calcule la concentration en ions hypochlorite dans l’eau fonctionnelle (90) sur la base d’un signal de sortie, calcule le rapport de l’acide hypochloreux et des ions hypochlorite dans l’eau fonctionnelle (90) sur la base du pH de l’eau fonctionnelle (90) et d’une constante de dissociation pKa de l’acide hypochloreux, et calcule la concentration en acide hypochloreux dans l’eau fonctionnelle (90) sur la base de la concentration en ions hypochlorite calculée et du rapport calculé.
(JA) 機能水濃度センサ(1)は、紫外光(11)を発する光源(10)と、次亜塩素酸、及び、次亜塩素酸から解離した次亜塩素酸イオンを含むpHが6以上9以下の機能水(90)が入れられる容器(20)と、受光素子(30)と、信号処理部(40)とを備える。信号処理部(40)は、出力信号に基づいて機能水(90)中の次亜塩素酸イオンの濃度を算出し、機能水(90)のpH、及び、次亜塩素酸の解離定数pKaに基づいて機能水(90)中の次亜塩素酸及び次亜塩素酸イオンの比率を算出し、算出された次亜塩素酸イオンの濃度、及び、算出された比率に基づいて機能水(90)中の次亜塩素酸の濃度を算出する。
