Abstract

The invention discloses a method capable of eliminating the influence of a reagent blank and rapidly detecting the content of chlorine dioxide in water. The method comprises the following steps: firstly, preparing a liquid-type chlorine dioxide detection reagent, then manufacturing a chlorine-dioxide standard color card without the reagent blank by a colorless and transparent PVC (Polyvinyl Chloride) plastic board, putting the chlorine-dioxide standard color card at the bottom part of a blank tube in testing, and reading the concentration of chlorine dioxide corresponding to the standard color card when the color is consistent to that of a sample tube, thereby obtaining the concentration of chloride dioxide in a water sample. The method disclosed by the invention has the advantages that if the method is adopted for carrying out detection on the concentration of chloride dioxide, the influence of the reagent blank on a detection result can be eliminated, and the method is especially suitable for on-site fast detection of chloride dioxide in water.

Description

technical field

[0001] The present invention relates to the field of water quality detection, in particular to a method for rapidly detecting chlorine dioxide content in water that can eliminate the influence of reagent blanks. Background technique

[0002] Chlorine dioxide (ClO 2 ) is the latest generation of high-efficiency, broad-spectrum and safe sterilizing and fresh-keeping agents recognized internationally at present, and is the most ideal substitute for chlorine preparations, and has been widely used in developed countries in the world. Drinking water treated with chlorine dioxide will not produce teratogenic, mutagenic, and carcinogenic chloroform that is usually produced when chlorine-containing disinfectants such as sodium hypochlorite are used, but skin contact or ingestion of solutions containing high concentrations of chlorine dioxide , may still cause strong irritation and corrosion.

[0003] The detection of chlorine dioxide in water mostly uses direct colo...
