Abstract

With the general purpose of testing various inorganic sensitive membranes for ISFET, the systems poly(acrylamide) (PAam)–xCdX2 (X=Cl, Br, I) have been studied for x≤0.5. The IR and Raman spectra show that the metal interacts with the oxygen atom of the amide group and allow the vibrations of the complexed CdX2 to be characterized. A possible structure is proposed.
