What are the conversion factors to express chlorine as another oxidizer?
Summary
Converting Chlorine to other oxidizers
Answer
Because DPD chemistry can be oxidized by compounds other than chlorine, it is possible to utilize the chlorine DPD curve to approximate the concentration of the analytes listed below. Multiply the measured concentration as chlorine by the conversion factor provided.

Chlorine to ozone - multiply by .68
Chlorine to Iodine - multiply by 3.58
Chlorine to Bromine - multiply by 2.25
Chlorine to KMnO4 - multiply by 2.23

For more accurate results utilize the  Hach Water Analysis Handbook for methods that are specific to ozone, iodine, bromine, and potassium permangante.
