Abstract
An apparatus for dispensing a liquid medium containing dissolved chlorine dioxide comprises a reservoir which defines a receptacle adapted for holding a precursor liquid medium having chlorine dioxide precursor dissolved therein and a tip assembly into which the precursor liquid medium passes after the precursor liquid exits the receptacle. The tip assembly comprises a chamber in which is located a promoter component effective to promote the generation of chlorine dioxide from the chlorine dioxide precursor in the liquid medium present in the chamber, an outlet providing a path for the liquid medium containing dissolved chlorine dioxide to exit the chamber, and an isolation assembly acting to effectively separate the precursor liquid medium in the reservoir from the promoter when it is desired that the precursor liquid medium from the reservoir be separated from the catalyst.
