Abstract
ABSTRACTThe sol-gel process can be used to produce porous inorganic matrices that
are doped with organic molecules. These doped gels can be used as a
quantitative method for the spectrophotometric determination of trace
concentrations of metallic ions. For the detection of hexavalent chromium,
malachite green was used as the dopant. Preliminary results indicate
concentrations on the order of 5 ppb are detectable using this method.
