“…Typically, chromium speciation analysis is conducted using separation techniques [8]. Unfortunately, these separation techniques, such as coprecipitation [9], liquid-liquid extraction [10], or chromatography [11], are insufficiently selective. Solid phase extraction (SPE) is a separation technique used to analyze complicated matrices or low-concentration analytes [12].…”

A new sorbent based on ion-imprinted polymers has been successfully synthesized to examine chromium(III) in environmental water samples. In this study, Cr(III)−IIPs was synthesized using Cr(III)−DPCO complex as a templating molecule, and ethylene glycol dimethacrylate (EGDMA), methacrylic acid (MAA), and benzoyl peroxide (BPO) as crosslinking agent, functional monomer, and radical initiator, respectively. The fabricated Cr(III)−IIPs polymer was characterized using Fourier transform infrared (FTIR) spectroscopy and Scanning electron microscope (SEM). The FTIR results confirm that Cr(III)−IIPs has been successfully synthesized. A peak at 495 cm-1 indicated the stretching vibrations of Cr−N. The firm peaks at 1732 cm-1 and 1163 cm-1 are assigned to C=O and C−O stretching vibrations of methacrylic acid. The broad and strong peak at 3483 cm-1 corresponded to hydroxyl bonds between the templating molecule and functional monomer. The SEM images revealed that the morphology of the polymer was irregular and large. The Imprinting factor (IF) values of Cr(III)−IIPs/NIPs−DPCO and Cr(III)−IIPs/NIPs were 3.12 and 1.53, respectively. The sorbent developed by this technique can be selective to the target ions.

“…cloud point extraction, solid phase extraction (SPE), ion exchange, hydride generation, and chromatography (10)(11)(12)(13)(14)(15)(16). Among these techniques, SPE for the preconcentration and separation of trace elements has achieved increasing application because of its simplicity, speed, high enrichment factors, rapid phase separation, and ability to combine with different detection techniques.…”

A new procedure for the determination of chromium species in polluted environmental samples by flame atomic absorption spectrometry was developed in this work. A new material containing 1,5-diphenylcarbazone included in a polymeric matrix was prepared and employed as a solid-phase extraction material for selective separation of Cr(III) ions under dynamic conditions. Chromium(III) ions were retained on this sorbent with high efficiency and repeatability (95 %, RSD = 1 %) from solutions with pH 9.0. The quantitative recovery of analyte was obtained with 0.1 mol L −1 EDTA. The concentration of Cr(VI) ions was calculated from the difference between the concentration of total chromium and Cr(III) ions. The prepared sorbent exhibits good chemical and mechanical stability, sorption capacity and selectivity towards Cr(III) ions in the presence of Cu(II), Ni(II), Mn(II) and Ca(II) ions. The accuracy of the separation method was proved by analysis of reference material of wastewater RES 10.2. The developed procedure was applied for chromium speciation analysis in municipal sewage samples.
