A new magnetic Fe3O4@SiO2@TiO2-APTMS-CPA adsorbent for simple, fast and effective extraction of aflatoxins from some nuts

APTMS-BCAD modified magnetic iron oxide for magnetic solid-phase extraction of Cu(II) from aqueous solutions

“…The modification of the magnetic Fe 3 O 4 @SiO 2 nanoparticles with APTMS and BCAD on the surface increased the density of the functional groups. Thus, it is thought that Cu(II) ions greatly increase the active binding sites [ 39 ]. Cu(II) or other metal ions are well known to be adsorbed onto adsorbent via coordination and electrostatic attraction [ 103 ].…”

“…After, this suspension solution was added to 1.2 g of BCAD compound and 0.6 mL of triethylamine and refluxed for 76 h with continuous stirring under N 2 gas. After the reflux period, the solid nanoparticle adsorbent in the suspension mixture was separated using an externally applied magnet, washed with copious amounts of methanol-toluene, and dried at 80 °C overnight, like in our previous study [ 39 ]. The magnetic FSAB nanoparticle adsorbent likely structure is depicted in Figure 1 .…”

Fluorine-Functionalized Triazine-Based Porous Organic Polymers for the Efficient Adsorption of Aflatoxins

“…To evaluate the performance of the M-F-POP-based MSPE-HPLC-FLD method, the adsorption capacity, adsorption time, and reusability of adsorbents, the LR, LODs, RSDs, and recovery of the method were compared with those of the previously reported methods (Table ). The LODs obtained by the M-F-POP-based method were lower than that of MSPE-HPLC-MS/MS, MSPE-HPLC-FLD, , D-μSPE-HPLC-UV, SPE-HPLC-UV, IMSPE-UPLC-MS/MS, and SPE-HPLC-FLD . Compared with SPE-HPLC-FLD, MSPE-HPLC-FLD, , D-μSPE-HPLC-UV, and SPE-HPLC-UV, the M-F-POP-based method had a wider linear range.…”

Rapid one-pot synthesis of magnetically separable Fe3O4–Pd nanocatalysts: a highly reusable catalyst for the Suzuki–Miyaura coupling reaction

“…[5][6][7][8] Magnetic Fe 3 O 4 NPs have the advantages of being environmentally and economically favorable, and can easily be separated with an external magnetic field, making them one of the widest researched magnetic nanoparticles. [9][10][11][12] However, for successful application of magnetic Fe 3 O 4 , two aspects must be taken into consideration in designing the catalyst. One aspect is that magnetic responsiveness should be improved, which is determined by factors of size, size distribution, shape and the chemical stability of iron oxide NPs.…”
