The invention relates to the technical field of
chlorine dioxide disinfection sterilization, in particular to a method for evaluating a
chlorine dioxide release rate. The method provided by the invention comprises the following steps: firstly forming a colorimetric card showing one-to-one correspondence between
chlorine dioxide release rates and color spots, then detecting color spots of to-be-evaluated samples in the same test environment and comparing with the colorimetric card, thus the
chlorine dioxide release rates of the to-be-evaluated samples can be directly read according to the colorimetric card. The method provided by the invention has the advantages that the to-be-evaluated samples only need to be placed in a test container for preset time after a color spot-release rate colorimetric card is formed, then
chromogenic reaction is performed by using wet
potassium iodide test paper, and reading is performed by comparing the colorimetric card, so that operation is simple and easy; and especially when the
chlorine dioxide release rate of a to-be-evaluated sample needs to be tracked for a long time, only simple
potassium iodide test paper
chromogenic reaction and comparison with a pre-prepared color spot-release rate colorimetric card need to be performed, so that evaluation work is greatly simplified and evaluation efficiency is improved. The method provided by the invention is easy to operate, low in cost and quick in result and is applicable to popularization and application.
