Amino-calix[4]arene modified graphite as an electrochemical interface for mercury(II) quantification

A new simple amino-calix[4]arene modified graphitic composite electrode have been prepared and employed in the form of thin film on glassy carbon electrode (GCE) surface as a sensing probe for the measurement of mercury(II) ions. In order to decipher the complexing ability of the modifier towards the metal ions analytical techniques such as cyclic voltammetry and differential pulse anodic stripping voltammetric are used
