    摘要: An ion exchange membrane for use in sensors which measure dissolved gases. Disclosed is a method for using ion exchangers in gas permeable membranes to maintain optimal conditions in the electrolyte contained within the sensor. This can greatly extend the lifetime and improve the stability relative to sensors of similar size and electrolyte volume that have been constructed using prior art.

    摘要: An amperometric membrane sensor that utilizes redox-carriers to transfer the redox potential of an oxidizing or reducing species to an electrode. The sensor consists of a membrane containing a first redox carrier, and a second redox carrier in the internal electrolyte of a membrane amperometric sensor. One implementation of this sensor utilizes a quinone carrier in a liquid membrane, and a vanadate carrier in the electrolyte to produce a sensor that responds to chlorine and chloroamine containing aqueous solutions. This strategy for the construction of an amperometric sensor allows the detection and quantification of redox-active membrane impermeant species.

    摘要: It has been found that certain chemicals such as peroxide may be concentrated in an aqueous solution by increasing the pH of a feed liquor to increase the amount of the chemcial in an ionized form, i.e. increase the ionized fraction and then separating the feed liquor by reverse osmosis through a reverse osmosis membrane into a retentate having an enhanced concentration of chemical in ionized form relative to the feed liquor and a permeate having a reduced concentration of chemical in ionized form relative to the feed liquor. The process is particularly suited to increasing the concentration of hydrogen peroxide.
