“…In recent years, potentiometric sensors based on MIPs have been successfully developed, while most of them are fabricated for ionic species [7,8]. In this work, we utilize the specific binding properties of MIPs to develop a potentiometric sensing methodology for measuring neutral phenols with high sensitivity and excellent selectivity.…”

The aim of this paper is to develop a potentiometric sensing methodology for sensitive and selective determination of neutral phenols by using a molecularly imprinted polymer as a receptor. Bisphenol A (BPA), a significant environmental contaminant, is employed as the model target. The BPA-imprinted polymer is synthesized by the semi-covalent technique and incorporated into a plasticized poly(vinyl chloride) membrane doped with the tridodecylmethylammonium salt. The present electrode shows a linear anionic potential response over the concentration range from 0.1 to 1 μM with a detection limit of 0.02 μM, and exhibits an excellent selectivity over other phenols. The proposed approach has been successfully applied to the determination of BPA released from real plastic samples. It offers promising potential in development of potentiometric sensors for measuring neutral phenols at trace levels.

The electrode carbon paste molecularly imprinted polymer (MIP) has been developed to analyze glucose by potentiometry. The MIP was made by mixing glucose as a template, methacrylic acid as monomer and ethylene glycol dimethacrylate as a crosslinker with the mole ratio of 1: 4: 12. The electrode made by mixing activated carbon, MIP, and paraffin with the ratio 50: 35: 15 (%, w/w) was observed to perform optimally. The results obtained show that analysis of glucose gives optimum results at pH 5 (without the pH adjustment). The analysis of glucose using electrodes carbon paste/MIP gives Nernst factor is 28.80 mV/decade, the measurement range is 10 -2 -10 -5 M and the limit of detection is 5.87.10 -5 M. In this study can be known that urea did not interfere the analysis of glucose using this method. The accuracy of this electrode is 70.7 -129% and the coefficient of variation is 0.06 -0.18% for the concentration range 10 -5 -10 -2 M. This electrode showed response time less than 2 minutes and could be used for 145 times.

Abstract. Molecular imprinting technology is a promising technique for creating recognition elements for selected compounds and has been successfully applied for synthesis of environmental pollutants such as simazine. Simazine is a pesticide ingredient that is commonly used in agriculture, which has devastating effects on the environment if used excessively. Molecularly imprinted polymer (MIP) provides cavities to form a particular space generated by removing the template when the polymer has formed. In this study, MIP using simazine as template had been made by the cooling-heating method and used as a material potentiometric sensor for detecting simazine. A template (simazine) was incorporated into a pre-polymerization solution that contains a methacrylic acid as functional monomer, an ethylene glycol dimethacrylate as cross linker, and benzoyl peroxide as initiator. Characterization was performed by scanning electron microscope (SEM) and fourier transforms infra-red (FTIR). The FTIR spectra of the MIP showed that the peaks of amine group decrease significantly, indicating that the simazine concentration decreases drastically. Characterization by SEM images showing the broadest pore size distribution with the highest number of pores in the MIP prepared under the heating time of 150 min. The MIPs therefore could be applied as a simazine sensor.
