“…In this way, by simply recovering the solid particles, remediation of aqueous media can be efficiently done. Using a similar concept, researchers have been working on the development of magnetic hybrid sorbents which can then be separated from the treated sample by means of a magnetic field . Graphene, carbon nanotubes, and MOF based hybrids with iron or iron oxide as magnetic phase have been studied, among others.…”

“…Magnetic solid phase extraction (M-SPE) is a dispersible solid phase extraction technique in which magnetic or magnetized materials are used as adsorbent substrate [77][78][79]. Compared with conventional solid phase extraction (SPE) fillers, nanoparticles have larger specific surface area and shorter diffusion distance, and only need to use a small amount of adsorbent and a short equilibrium time to achieve low concentration of microextraction, with very high extraction capacity and extraction efficiency.…”

Magnetic nanomaterials (MNPs) have been widely used in the detection of pollutants in the environment because of their excellent nano effect and magnetic properties. These intrinsic properties of MNPs have diversified their application in environmental contaminant detection. In this paper, the research status quo of the use of MNPs in detecting organic and inorganic contaminants from wastewater and soil is reviewed. The preparation method and modification technology of magnetic nanoparticles are also described in detail. The application prospect of magnetic nanoparticle composites in the detection of contaminants in water and soil is discussed. Compared with traditional detection methods, MNPs are more accurate and efficient in pollutant enrichment. Moreover, the biological synthesis of MNPs was proven to be eco-friendly and aided in sustainable development. The study shows that MNPs have good application prospects in soil pollution detection, but the mechanism still needs to be investigated to realize their popularization and application.

“…Although Pd and Ni have excellent electron transfer effects, Cu is more feasible in catalytic applications owing to three advantages: 1) cheapness; 2) exceptional accessible; last but not least, enable electrons transfer faster when combined whit other metal as the result of its being in the transition region [42]. Various carriers, such as functional kaolin [43], bentonite [44], attapulgite [45], and activated carbon (AC) [46][47][48] were applied to disperse nZVI due to their low cost. Among the above supporters, AC is not only an excellent adsorbent with trace oxygen-containing functional groups located on the surface, but can activate PS to produce •SO 4 as well [49,50].…”

Advanced oxidation process (AORs) is an effective method to remove a wide range of organic contaminants. However, an outstanding catalysis is needed to generate more free radicals. In this work, nano zero-valent iron (nZVI) modified with activated carbon and copper (AC-nZVI/Cu) was synthesized by liquid-phase reduction, and used to catalyze persulfate (PS) to remove norfloxacin (NOR). The effect of various factors, such as diverse adsorbents, pH, temperature, PS dosage, adsorbent dosage, and inorganic anions, on NOR removal efficiency were investigated. The results show that 30 mg/L NOR can be easily removed by 0.5 g/L AC-nZVI/Cu at 313 K through activating 0.5 mM PS, and the removal efficiency is as high as 96.84%. The electron paramagnetic resonance (EPR) analysis proves that numerous sulfate free radicals (•SO4 -) appear at the initial stage of the removal process. Furthermore, the quenching experiments manifested that •SO4was the predominant radical special in acidic conditions, while adsorption of NOR was predominant under alkaline conditions. Importantly, compared with nZVI, AC-nZVI/Cu has excellent long-term stability because of the introduction of activated carbon and copper. The study laid the groundwork for further development of adsorbent and activator based on nZVI.
