Novel Zeolitic Imidazolate Frameworks Based on Magnetic Multiwalled Carbon Nanotubes for Magnetic Solid-Phase Extraction of Organochlorine Pesticides from Agricultural Irrigation Water Samples

Abstract: Magnetic solid-phase extraction is an effective and convenient sample pretreatment technique that has received considerable interest in recent years. A lot of research indicated that magnetic nanocarbon-material-based composites have good application prospects as adsorbents for magnetic solid-phase extraction of pesticides. Herein, a novel zeolitic imidazolate framework based on magnetic multiwalled carbon nanotubes (M-M-ZIF-67) has been prepared as an adsorbent for magnetic solid-phase extraction of nine orga… Show more

“…3C . The adsorption band at 584 cm −1 in all the spectra can be attributed to the Fe–O vibration, suggesting that the MG/PDA nanocomposites were well contained Fe 3 O 4 nanoparticles 20 . In MG/PDA spectrum, the adsorption band at 1582, 1489, and 1281 cm −1 corresponding to the stretching vibrations of C=C, N–H, and C–O of PDA, respectively 21 .…”

“…MWCNTs are also being successfully explored in environmental applications, such as for water quality control and treatment. Two interesting reports [9,10] are included in this Special Issue, both of which are related to the use of MWCNTs as adsorbents of contaminants, namely nonylphenol [9] and organochlorine pesticides [10] from source waters and agricultural irrigation water samples, respectively. The contributing authors [9,10] characterized the main operational parameters and the type of adsorption demonstrating the applicability of MWCNTs for the removal and extraction of contaminants from water samples.…”

“…Therefore, monitoring of the OCP residues in agricultural products is of great importance with regard to food safety and the protection of human health. The analytical techniques for the determination of OCPs are generally based on GC, using specific detectors such as an electron capture detector [1][2][3], and on MS [4][5][6][7]. However, OCPs are usually present in low concentrations and therefore, require highly effective sample preparation procedures prior to instrumental analysis.…”
