Abstract

We report here a new voltammetric method for the sensitive and selective determination of Hg²⁺ based on rational covalent functionalization of graphene oxide with cysteamine to form cysteamine-functionalized graphene through nucleophilic ring-opening reaction between the epoxy of graphene oxide and the amino group of cysteamine in KOH solution.
