Synthesis of copper(II) ion‐imprinted polymers via suspension polymerization

Abstract

Funding informationScience Achievement Scholarship of Thailand (SAST); Mae Fah Luang University (MFU) Copper(II) (Cu 2+ ) ion-imprinted polymers were prepared by suspension polymerization using 2.5 mmol of copper(II) sulfate pentahydrate as the template ion, 5 mmol of 4-vinylpyridine and methacrylic acid as functional monomers, 20 mmol of ethylene glycol dimethacrylate as the cross-linker, 1 mmol of 1,1′-azobis (cyclohexanecarbonitrile) as the initiator in the porogen of 10 mL of toluene, and hydroxypropyl methyl cellulose as a stabilizer in the polymerization reaction. The obtained polymers were used to quantify Cu 2+ ion by using flame atomic absorption spectroscopy. Chemical structure, morphology, crystalline structure, and surface area of polymers were investigated by Fourier transform infrared spectroscopy, scanning electron microscope, X-ray diffraction, and Brunauer-Emmett-Teller respectively. The diameters of the synthesized polymer particles were about 250 nm. The Cu 2+ ion-imprinted polymers illustrated good recognition property and selective adsorption ability with Cu 2+ higher than Mn 2+ and Fe 2+ . Thus, this work could be applied as a sorbent from the enrichment of Cu 2+ ions in analytes.

“…The results of the synthesized IIP is compared on various parameters with other previously reported Cu(II) imprinted materials and demonstrated in Table 5. Chaipuang et al have reported Cu(II) polymer beads through suspension polymerization and has shown capacity of 0.495 mg g −1 , in 24 h 31 . Kuras et al, developed Cu(II)‐IIP through precipitation polymerization having a capacity of 14.8 mg g −1 32 .…”

Effect of ethylene diamine tetra‐acetic acid and functional monomers on the structure and adsorption properties of copper (II) ion‐imprinted polymers

“…The effects of pH, time, concentration, and selective properties on the adsorption capacity of polymer particles were investigated using FAAS (Hitachi‐Z‐5000) 13 . Gas flow used for flame analysis consisted of air, 15 L min −1 and acetylene, 2.20 L min −1 .…”

“…Polymer materials are used to produce IIPs because they are easy to synthesize, have good environmental stability, and can be reused with high selectivity toward targeting ions 9 . The influence of ligands, functional monomers, and crosslinkers on IIPs has attracted research attention with separation and determination of arsenic, cadmium, cobalt, copper, iron, potassium, lithium, nickel, lead, and zinc ions reported using IIPs 10‐19 . In IIP composite preparations, most reports applied ligands for complexing with template ions.…”
