Total residual chlorine |
摘要 |
A method of monitoring the total residual chlorine in solution. A sample stream is extracted from the solution and mixed with a reagent stream containing a dissociated complex of alkali metal ion and iodide ion, and an excess amount of iodide ion. Iodide ion reacts with all the residual chlorine in the sample stream and is converted to iodine. The activity of iodine is then measured in the resultant mixed stream with a first and second electrochemical potentiometric electrode, the first electrode having a noble metal oxidation-reduction element, and the second having an iodide sensitive membrane element. The total residual chlorine is determined from the activity of the iodine.
