Certain water samples, such as those containing detergent, may form an emulsion when oil in water extraction into a solvent is done. In order to ensure an accurate measurement, the emulsion must be broken. Six techniques are described that can be used for reducing an emulsion in order to obtain valid oil in water measurements -- whether the analysis is done by infrared, gravimetric ... |

Although this method of disinfection has its advantages, it also requires a certain level of monitoring, albeit less so than chlorine. For example, it is necessary to monitor not only the specified limits for chlorine dioxide but also the chlorite that forms during disinfection.
