More Information
Summary:Method to prepare fluids (liquids and gases) containing pure chlorine dioxide which is not contaminated by the starting materials or the byproducts of the chlorine dioxide synthesis or to deliver pure chlorine dioxide into any medium capable of dissolving chlorine dioxide, wherein the chlorine dioxide generated in the process is transported across a pore free polymeric membrane via selective permeation into the target medium. Apparatus to realize the said method, wherein the generation of chlorine dioxide is carried out in such a reactor where some or all walls comprising the reactor, or the walls of a permeator unit attached to the reactor, are made of the said pore free polymer, characteristically some kind of silicone rubber, which is highly permeable to chlorine dioxide, but which is practically impermeable for the acidic and corrosive reagents used for the chlorine dioxide synthesis, its permeability being at least 3 orders of magnitude lower for these contaminating components compared to that of chlorin
