Hence, the measurement of
mercury at trace level is very important and mandatory due to its
low prescribed level. Amide functional groups are highly specific
towards mercury due to the presence of amide nitrogen and carbonyl
oxygen as potential donor atoms [11]. 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.
