In this letter, a novel chemically
modified amino-calix[4]arene-graphite composite material has been
used as a sensing platform electrochemical sensor in mercury(II) ion
quantification. The presence of functional motifs (CONH groups) on
the surface of calixarene-graphite composite provides a good sensing
ability in presence of mercury(II) ion and it has been successfully
applied to real sample matrices like water and industrial effluents.
