Fourier Transform Infrared (FTIR) and proton nuclear magnetic resonance (1H NMR) spectroscopy were used in the characterization of the obtained copolymer. Under the optimum conditions, several validation variables such as uncertainty measurement, selectivity, robustness, precisions, matrix effects and accuracy were investigated. Taking an adsorption time of 15 min, detection limits of 0.04 μg L −1 and 0.2 μg L −1 and 7.9 μg L−1 and enrichment factors of 145 and 110 were obtained for Mn(II) and Zn(II), respectively. The method was successfully applied to the analysis of Mn(II) and Zn(II) in foods and vegetables.
