Embodiment 1

[0027] 1. Preparation of gradient samples containing chlorine dioxide:

[0028] Take the blank milk, divide it into several portions and add different amounts of commercially available solid chlorine dioxide compound disinfectant to make 0%, 0.00002%, 0.00004%, 0.00008%, 0.0001%, 0.0002%, 0.0005%, 0.001%, A 0.002% gradient sample containing chlorine dioxide is to be tested.

[0029] 2. Detection limit verification

[0030] According to the above method, the test data is as follows:

[0031] Serial number

[0032] 2

[0033] The detection limit of this method for chlorine dioxide residue detection is 0.0002%, the detection limit is low, the method is more sensitive, and meets the needs of use.

Abstract

The invention relates to a test method, in particular to a rapid qualitative test method of chlorine dioxide in milk, and also relates to a rapid qualitative detection reagent kit of chlorine dioxide. The invention belongs to the technical field of the chemical composition detection. A qualitative adulteration test method of the chlorine dioxide performs the detection according the following procedures that: a test paper strip is immerged into a milk sample, whether the chlorine dioxide is remained or not in the milk sample is judged according to the color change of a test paper strip after being taken out, and the detection limit of the method is 0.0002 percent.

Description

Technical field [0001] The invention relates to a detection method, in particular to a rapid qualitative detection method of chlorine dioxide in milk, and also to a rapid qualitative detection kit for chlorine dioxide. It belongs to the technical field of chemical composition detection. Background technique [0002] At present, there is no national standard for C102 in drinking water and its supporting test methods, and there is no test standard for chlorine dioxide in milk. Through reviewing relevant literature, it is concluded that the detection methods of chlorine dioxide include amperometric titration, iodometric titration, ultraviolet-visible spectrophotometry, flow injection analysis, polarography and other quantitative detection methods. These methods have relatively low detection limits. Low and sensitive, but the inspection procedure is complicated and not suitable for online inspection applications. The invention can quickly and qualitatively detect milk mixed with chlo...
