Abstract

The recently developed method of immobilization of organic reagents in porous silica glass via the sol-gel procedure is used in order to produce quantitative photometric sensors. Silica glass detectors doped with 1-nitroso-2-naphthol for detection of cobalt ions and o-phenanthroline for determination of divalent iron serve as test cases that demonstrate the advantages and the current limitations of the immobilization procedure.
