Hojatpanah, Mohammad Reza published the artcileConstruction and application of a novel electrochemical sensor for trace determination of uranium based on ion-imprinted polymers modified glassy carbon electrode, Recommanded Product: Trimethylolpropane triacrylate, the publication is Chemosphere (2022), 133435, database is CAplus and MEDLINE.
In the present work, a novel electrochem. sensor modified glassy carbon electrode with ion-imprinted polymers (IIP-GCE) was applied for uranyl ions (UO2+2) determination Surface modifier was synthesized through precipitation polymerization method, using acrylic acid as a monomer, benzoyl peroxide (BPO) as initiator, and trimethylolpropane triacrylate (TMPTA) as crosslinker. A new uranyl-trans-3-(3-pyridyl) acrylic acid complex was employed, serving as an active and specific site on the synthesized modifier. Next, the synthesized modifier was characterized using X-ray diffraction (XRD), SEM (SEM), and Fourier Transform IR Spectroscopy (FT-IR) techniques. UO2+2 ions were detected using a differential pulse adsorptive anodic stripping voltammetry method. Under the optimized conditions (pH = 8.0, pre-concentration time = 10 min and pre-concentration potential = -0.30 V), the modified electrode exhibited linear behavior in the interval of 1.27-95.49μg.L-1 with a limit of detection (LOD) of 0.43μg.L-1. Also, the constructed ion-imprinted sensor showed a successful application for determining UO2+2 ions with recovery range of 97.6-101% in real samples.
