Abstract: A method for detecting organic molecules such as benzene, xylene, ethylbenzene and toluene present in trace quantities in aqueous solutions is provided. The method uses a zeolite having a multiple cage structure, specifically cages of two different volumes. The zeolite is chosen so that the organic molecules are able to access the zeolite on the basis of size. The small cages contain electroactive ions therein and the larger cages contain electroinactive counter cations therein. An aqueous liquid sample to be tested for small molecules is flowed into contact with the zeolite whereby at least some of the electroactive ions in the small cages are released into the aqueous liquid sample by small molecules entering the larger cages and coupling with the electroactive ions in the smaller cages and exiting the zeolite.

Abstract: Provided is a method and apparatus for detecting electroinactive ions, and electroinactive ions solvated by small molecules including water. The method and apparatus utilizes a microporous ion exchange material such as a zeolite containing initially an electroactive species contained within the pores. The method operates on the principle that when charged species present in solution can access the pores of the microporous material, an ion-exchange reaction will occur whereupon the electroactive species will exit the microporous material, being replaced by the charged species. The electroactive species, upon exiting the microporous material, undergoes electrochemical reduction or oxidation at an electrode having a sufficiently high potential applied thereto. The method and detector disclosed herein is size selective since for example zeolites with a pore size comparable to that of the solvated ion to be detected but smaller than other electrolyte components can be utilized.
