Visualization agent, method for determining the effectiveness of disinfectants using this, and method for detecting carbonation

摘要

PROBLEM TO BE SOLVED: To provide a method for easily determining whether or not the effect of a disinfectant such as slaked lime is lost due to carbonation. SOLUTION: This is a method for determining the effectiveness of a disinfectant containing slaked lime, fresh lime, etc. as an active ingredient, and is a visualization agent which is a solution containing lithomas and a citrate buffer having a concentration of 30 mM or more in the disinfectant and having a pH of 6 or less. The step of applying the disinfectant, the step of detecting the coloration of the disinfectant within the determinable time range after applying the visualization agent, and the determinable time range is the disinfectant immediately after preparation as a positive control and the negative control. When the visualization agent was applied to each of the carbonated disinfectants, the positive control was blue-purple to blue, while the negative control was red to magenta. The effect of the disinfectant is maintained when the coloration from bluish purple to blue is detected, and the effect of the disinfectant is reduced when the coloration from red to magenta is detected. The method comprising the step of determining that there is. [Selection diagram] Fig. 1
