“…After adding NaCl, it was found that the maximum adsorption capacity increased with the concentration of NaCl; the maximum adsorption capacity attained 919.8224, 949.7236, 986.4689 and 994.50 mg g −1 when the NaCl concentrations were 50, 100, 150 and 200 mg g −1 , respectively. This phenomenon indicates that the ionic concentration would affect the adsorption performance and that adsorption capacity increased with the increase of ionic concentration . This might be attributed to the ionic solution enhancing the activity coefficient of MCMP and decreasing the solubility of MB, resulting in promoting the adsorption of MB.…”

The result of the ionic strength experiment showed that MCMP has excellent adsorption performance in deionized H 2 O, that adsorption capacity would increase further with increased ionic strength, and that MCMP has great potential value in wastewater treatment.…”

BACKGROUND A magnetic conjugated microporous polymer (MCMP) composite was designed with bromo groups of CMP and amino groups on the surface of Fe3O4 nanoparticles that acted as promising adsorbents for wastewater treatment. Fe3O4 nanoparticles were successfully bonded on the predesigned CMP material to form the MCMP by means of a new and simple nucleophilic substitution reaction in organic media. RESULTS The MCMP could be separated by applying an external magnetic field because of the Fe3O4 nanoparticles. It exhibited sufficient dye adsorption for methylene blue (MB) with a high sorption capability of 869.43 mg g−1 in aqueous solutions. The recovery and reusability of MCMP were >70% after six cycles of desorption and regeneration, indicating that the MCMP had excellent cycle stability. The magnetization saturation strength of MCMP was 13.5 emu g−1 which was sufficient to be magnetically separated from wastewater using artificial magnetic fields. CONCLUSION The MCMP possessed excellent adsorption capacity and dispersibility, and good recyclability after banded with functionalized Fe3O4 nanoparticles. The excellent properties of MCMP indicated that it could be used as an adsorbent with great application potential for quick separation of water pollutants such as dyes in wastewater treatment. © 2019 Society of Chemical Industry

“…The adsorption of the aromatic molecules to the GO surface occurs via π–π interactions, and so the subsequent adsorption of tetracycline molecules onto the GO nanocomposite was driven by π–π and cationic‐π interactions. Taking this into account, several magnetic graphene based nanocomposites have been investigated for the removal of antibiotics from aqueous solution . Li and co‐workers have prepared a magnetic material by grafting a multidentate chelating agent (nitrilotriacetic acid) to an iron oxide and GO nanocomposite .…”

Inorganic nanoparticles (NPs) have emerged in the last decades as key materials for a number of technologies. In particular, noble metal (Ag, Au) and iron oxide NPs have revealed important applications due to their plasmonic and magnetic properties, respectively. Among these applications, this review provides, on one hand, an overview on the use of colloidal metal NPs in surface enhanced Raman scattering (SERS) chemical analysis and, on the other hand, the application of iron oxides as a new class of nanosorbents for water pollutants. These distinct types of NPs are the main building blocks to produce [a] Raman spectroscopy is a powerful analytical tool for chemical characterization, providing information about molecular structure, surface processes, and interface reactions. [31,32] Raman spectroscopy is based on the inelastic scattering of photons by chemical species and materials (Raman scattering). Among the incident photons that hit the sample only a small portion is inelastically scattered, i.e. comes out at a different frequency from the incident light. The spectral information is based on the detection of these scattered photons that are recorded as energy shifts (Raman shifts) from the wavenumber of the elastic scattered photons (Rayleigh scattering). Each band in the Raman spectrum can be assigned to a vibrational mode (or Paula
