Matrix-dispersed magnetic molecularly-imprinted polyaniline for the effective removal of chlorpyrifos pesticide from contaminated water

Abstract

An efficient magnetic molecularly-imprinted polymer adsorbent for removal of chlorpyrifos organophosphate pesticide from water is reported.

Optical Ammonia-Sensing Probe Based on Surface-Plasmon Resonance of Silver-Nanoparticle-Decorated Superparamagnetic Dendritic Nanoparticles

“…The XRD diffractogram of Fe 3 O 4 NPs reveals a typical cubic magnetite crystal. The diffraction peaks were perceived at 2θ values of 30.1° (220), 35.5° (311), 43.2° (400), 53.5° (422), 57.1° (511), and 62.7° (440) [19]. The same diffraction peaks could be observed in the diffractogram of NP-III, although some peaks were slightly shifted, minimized, or completely diminished.…”

“…3E and J appears as a ring pattern, which indicates that the synthesized nanomaterials are polycrystalline [19]. In addition, the presence of single spots in the SAED pattern of NP-II and NP-III may imply that the sample material is at the nanoscale [19].…”

Azo-functionalized superparamagnetic Fe3O4 nanoparticles: an efficient adsorbent for the removal of bromocresol green from contaminated water

“…This finding is consistent with the results obtained from the Scatchard analysis in the previous section. 15 …”

“…Superparamagnetic magnetite nanoparticles were synthesized by the modied solvothermal method in ethylene glycol. 3,15,23 Briey, 2 g of FeCl 3 $6H 2 O and 6 g of anhydrous sodium acetate were dissolved in 65 mL of ethylene glycol. This mixture was transferred to a Teon-lined solvothermal reactor and then heated to 200 C in the oven (Heraeus, Thermo Electron Corporation, Germany) for 12 h. Aer the reaction, the solvothermal reactor was cooled to room temperature, and the formed black magnetite precipitate was collected with a strong magnet.…”

“…In one of our prior studies, BCG and another triphenylmethane dye (bromophenol blue) were removed from contaminated water by polyethyleneimine-coated Fe 3 O 4 nanoparticles. 3 Superparamagnetic iron oxide nanoparticles (SPIONs) are considered a versatile material in various applications such as drug delivery, [10][11][12] bio sensing, 13,14 water purication, 3,15 solidphase extraction, 16,17 and even bio imaging. 18,19 SPIONs are known for their biosafety, easy functionalization, superparamagnetic properties, high stability, low cost, facile mass production, among other nanomaterials.…”
