| 論文概要 | Decolorization of curcumin-sorbed plastic plates by gaseous hypochlorous acid (HOCl (g)) was studied to assess whether HOCl (g) could penetrate into various kinds of plastic materials. HOCl (g) was vaporized from a silicone rubber tubes containing weakly acidic hypochlorite solution. When the curcumin-sorbed plastic plates were exposed to HOCl (g), curcumin in plastics was significantly decolorized markedly, depending on the treatment time. These results indicated that HOCl (g) molecules could penetrate into plastic materials with oxidizing power. | |

| 論文概要 | Kinetics of the stripping process of hypochlorous acid was studied in a forced-air vaporizing humidifier fed with sodium hypochlorite solution (NaOCl). Gaseous HOCl concentration, [HOCl (g)], was monitored using a chlorine gas detector equipped with a controlled potential electrolysis sensor. Volatilization of HOCl was shown to follow the first-order kinetics. It was also confirmed that the amount of free available chlorine (FAC) components volatilized from NaOCl solution depended strongly on HOCl (aq) concentration. These findings suggest that a time variation in the [HOCl (g)] of outlet air can be predicted by controlling the FAC concentration and pH of the NaOCl solution at constant air-flow rate. | |

| 論文概要 | The indoor concentration distributions of gaseous hypochlorous acid (HOCl(g)) were measured during the operation of a forced-air vaporizer fed with weakly alkaline hypochlorite solutions (pH 8.5) of 100 mg/L in 75-m3 room. HOCl(g) molecules were distributed almost uniformly throughout the room at each operation time. The HOCl(g) concentrations were within a range of 12 to 22 ppb, which were lower by at most one twenty-third than occupational exposure limit value of chlorine, i.e., 500 ppb. Viable bacterial cells, attached to a wet agar plates, decreased gradually with increase in the exposure time to HOCl(g), giving the logarithmic reduction more than 2.8-log within 2-h operation. These data indicated that low concentrations of HOCl(g) had a moderate bactericidal action against bacterial cells even if HOCl(g) concentrations were very low and safety level for the human body. | |

| 論文概要 | A forced-air vaporizing humidifier with alkaline sodium hypochlorite (NaOCl) was operated under ammonia ambient in a confined space. Ammonia in a gas phase was incorporated into the humidifier, and it was dissolved in the NaOCl solution and converted rapidly into inorganic chloramine (ICA). The amount of gaseous ICA(g) in outlet air from the humidifier was larger than that of gaseous hypochlorous acid (HOCl (g)). The efficacy of ICA (g) in inactivating Cladosporiumu cladsporioides spores on agar plates and in solutions was comparable to that of HOCl (g). It was indicated that gas-phase ammonia was removed efficiently by the humidifier, and there was little influence of the formation of ICA had on the inactivation efficacy against fungal spores. | |

| 論文概要 | The bactericidal action of gaseous hypochlorous acid (HOCl (g)) against Staphylococcus epidermidis in aerosols was examined in a confined space. The relative logarithmic reduction of viable cells depended on the product of the HOCl (g) concentration and time, and the rate of inactivation increased with increasing in the levels of relative humidity. There was little effect of temperature on the bactericidal activity of HOCl (g). These results indicated that the controlling HOCl (g) concentration and relative humidity in a confined space is one of the important factors determining the bactericidal efficacy against S. epidermidis in aerosols. | |

| 論文概要 | Gaseous hypochlorous acid (HOCl (g)) was generated by a forced-air vaporizing humidifier fed with pH-controlled sodium hypochlorite solution. Vibrio parahaemolyticus cells on 2.5% NaCl-agar plate, a non-nutritive plate, were exposed directly to air containing HOCl (g) at low concentrations less than 50 ppb. After 30-min exposure to HOCl (g), a 3.6 log reduction in viable cells was achieved, and logarithmic reduction dependent on the product of the HOCl (g) concentration (C) and time (t)). In the presence of tryptic soy broth (TSB) and peptone, bactericidal action of HOCl (g) decreased markedly, depending on their concentrations. Although mucin had a high reactivity with chlorine in solution, there was no influence of mucin on the bactericidal action of HOCl (g) because of the loss of the diffusivity of mucin in the agar gel. It was demonstrated that HOCl (g) exerted a good bactericidal action, but its efficacy decreased markedly in the presence of diffusive chlorine-consuming organic substances. | |

| 論文概要 | The preparation of simple indicator for the detecting gaseous haypochlorous acid (HOCl (g)) was examined using a glass fiber filter and potassium sulfamate. HOCl (g) molecule was entrapped by sulfaminate adsorbed on the glass fiber surfaces, thereby being converted into chlorosulfamate and stably retained. Glass fiber filter entrapping HOCl (g) was reacted with total chlorine reagent, and the color of the filter was measured with a spectroscopic colorimeter. The filter could detect HOCl (g) sensitivity both in gas-phase of a closed glass vial containing sodium hypochlorite (NaOCl) solution, and in outlet air of a forced-air vaporizing humidifier fed with NaOCl solution. A good linear correlation between the product of HOCl (g) concentration and time, measured by a chlorine detector, and the amount of HOCl (g) entrapped in the indicator was obtained. These data indicated that the indicator prepared is a useful tool for detecting and measuring the amount of gaseous HOCl in contact with a solid surface. | |

| The preparation of simple indicator for the detecting gaseous haypochlorous acid (HOCl (g)) was examined using a glass fiber filter and potassium sulfamate. HOCl (g) molecule was entrapped by sulfaminate adsorbed on the glass fiber surfaces, thereby being converted into chlorosulfamate and stably retained. Glass fiber filter entrapping HOCl (g) was reacted with total chlorine reagent, and the color of the filter was measured with a spectroscopic colorimeter. The filter could detect HOCl (g) sensitivity both in gas-phase of a closed glass vial containing sodium hypochlorite (NaOCl) solution, and in outlet air of a forced-air vaporizing humidifier fed with NaOCl solution. A good linear correlation between the product of HOCl (g) concentration and time, measured by a chlorine detector, and the amount of HOCl (g) entrapped in the indicator was obtained. These data indicated that the indicator prepared is a useful tool for detecting and measuring the amount of gaseous HOCl in contact with a solid surface. | |

| 論文概要 | Gaseous hypochlorous acid (HOCl) volatilized from sodium hypochlorite (NaOCl) solution was measured using a chlorine gas detector equipped with a controlled potential electrolysis sensor. Glass vials containing NaOCl solutions of different pHs and free available chlorine (FAC(aq)) concentrations were allowed to stand statically at 35 ℃ for 2 h. Equilibrium gas-phase HOCl concentration increased with decreasing pH, and with increasing FAC(aq) concentrations of NaOCl solutions. A good linear correlation between the concentration of HOCl (aq) in the NaOCl solutions and gaseous HOCl concentration was obtained. Gaseous HOCl could be measured successfully at least in the range of 10 to 1,200 ppb. A forced-air vaporing humidifier fed with NaOCl solutions of different HOClaq concentrations was operated, and gaseous HOCl in outlet air was measured. It was also found that gaseous HOCl concentration in outlet air depended on the HOClaq concentration. These data indicated that the chlorine gas detector is a useful apparatus for measuring gaseous HOCl simply in a room. | |
