چکیده
Herein, a carbon ionic liquid electrode (CILE) incorporated with Cu2+ ion-imprinted polymeric nanoparticles is explored for the voltammetric determination of Cu2+ ions. The procedure is based on the interfacial preconcentration of Cu2+ on an imprinted polymer modified CILE through the surface coordination effect. The modified electrode exhibited a significantly increased sensitivity and selectivity for Cu2+ compared with the non-modified electrode. The effects of various parameters, such as the amount of ionic liquid, graphite and, IIP nanoparticles, the effect of Cu2+ extraction conditions on the electrode response, the accumulation potential and the accumulation time were investigated. The modified electrode showed a linear voltammetric responses to Cu2+ in the ranges of 25-1250 nM with a limit of detection (LOD) of 9.4 nM (S/N =3). The interference experiments showed that Cu2+ signal was not interfered in the presence of some potential interfering ions and organic species. Moreover, this electrode presented the high sensitivity and excellent selectivity compared with previously reported methods in the area of electrochemical detection of Cu2+. These results demonstrate the feasibility of using the prepared Cu2+-imprinted polymer/CILE for efficient determination of Cu2+ in water samples.
