Method of preparing, storing, transporting and testing chlorine dioxide solutions

摘要

Chlorine dioxide solutions are stabilized and prepared for storage, transportation, and testing. Each solution is separated into two samples. Chlorine dioxide is removed from one sample and then each sample is stabilized and prepared such that each sample contains only oxidized and/or reduced forms of chlorine dioxide. The stable samples may be stored, transported, and tested for chlorine dioxide. The samples are tested for the oxidized and/or reduced forms of chlorine dioxide by known methods, and mass balance equations are used to determine the concentration of chlorine dioxide in the original sample before stabilization and preparation.

主权项

1. A method for preparing and stabilizing chlorine dioxide samples for transport, storage, or testing, which comprises taking at least two samples, Sample 1 and Sample 2, from a chlorine dioxide solution to be tested, the samples then being processed as follows:
stripping the chlorine dioxide from Sample 1, and raising the pH of Sample 2 so as to completely convert the chlorine dioxide in solution to other stable chlorine species.
