Abstract

The invention discloses a chemical indicator monitoring the disinfection effect of an oxidized disinfectant. The chemical indicator is prepared from an indicating compound and an ink composition. Theindicating compound is triarylmethane pigment, and the mass percentage of the indicating compound to the ink composition is (6-10%) to (90-94%). The color of the triarylmethane pigment can change obviously when being exposed an oxidized disinfectant disinfection process. The method for monitoring the oxidized disinfectant disinfection process comprises the following steps that the chemical indicator and a to-be-disinfected object are placed under a same disinfection condition; color changing of the chemical indicator is observed to judge a disinfection effect, when the chemical indicator is exposed to a wet oxidized disinfectant, especially ozone, the color of the chemical indicator changes obviously; and when the chemical indicator is exposed to a dry oxidized disinfectant or oxygen, thecolor does not change. The chemical indicator provided by the invention can rapidly monitor the disinfection result, has the obvious color indicating change, and has the relatively good indicating effect.

Description

technical field [0001] The invention belongs to the technical field of chemical indicators, in particular to a chemical indicator and a monitoring method for monitoring the disinfection effect of an oxidized disinfectant. Background technique [0002] Disinfection is needed in many fields, especially in medicine. Ozone is an oxidizing disinfectant, and its disinfection effect will be affected by factors such as humidity and temperature. Ozone can be sterilized at low temperature or room temperature, and ozone is easy to decompose at high temperature, so ozone does not require high temperature during disinfection, which is an advantage of ozone disinfection. Of course, it is also very important to monitor whether the ozone disinfection process achieves the disinfection effect. [0003] The design principle of the chemical indicator is that a characteristic color change occurs according to one or more physical conditions in the disinfection cabin. Chemical indicators are us...
