Abstract
Composite reactive articles are useful for quantifying cyanide ions in solution. The composite reactive articles can be porous reactive supports comprising an inert substrate having immobilized thereon finely divided gold. The porous reactive supports can be particulate, porous fibrous membranes or solution-cast membranes. Alternatively, the composite reactive articles can comprise porous fibrous membranes having enmeshed therein the aforementioned porous supports which can be in particulate or fibrous forms.
