Carbon nanotube-based ion imprinted polymer as electrochemical sensor and sorbent for Zn(II) ion from paint industry wastewater

A novel technique was presented to embed Zn(II) ion imprinted and nonimprinted polymers using various approaches for its sensing and sorption. Ion imprinted and nonimprinted polymers were fabricated by layering on MWCNTs or by bulk imprinting and characterized. Here Zn(II) ion was template, acrylic acid as monomer and N,N-methylene-bis-acrylamide as crosslinker. The electrochemical performance of electrode modified with imprinted and nonimprinted polymers were scrutinized and optimized with cyclic voltammetry (CV). The limit of detection for Zn(II) ion was found to be 1.32?×?10^?4?µM by differential pulse voltammetry (DPV). The applicability of the system was checked with paint industry wastewater.
