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 th...

Description
Summary: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. •The proposed sensor is novel and covalently modified interface.•Easy fabrication.•Provides good reproducibility.•Very low detection limit(nanomolar level).•Applied to different sample matrices.
