Material Design of a Chromium Imprinted Polymer and its Application as a Highly Selective Electrochemical Sensor for Determining Chromium Ion at Trace Levels

چکیده مقاله

This study investigates the development of a Cr (VI)-selective electrode based on Cr (VI) imprinted polymer nanoparticles and its application in detection of chromium ions by differential pulse voltammetry. In methanol, precipitation polymerization of meta-acrylate acid (the functional monomer), 2, 2’-azobisisobutyronitrile (the initiator), ethylene glycol dimethacrylate (the cross-linker), 1, 5-Diphenylcarbazide (the chromium-binding ligand), and chromium ions (the template ion) produced IPNPs. After polymerization, Cr (VI) was leached out from the polymer nanoparticles using NaOH/EDTA 0.5/0.1 molL
