“…After the adsorption is accomplished, the nanoparticles can be easily separated from the water by the application of a magnetic field. Hao et al [19] showed that the prepared the γ-Fe 2 O 3 @C nano composite (20 nm) was able to remove approximately 80% of the congo red (CR) within 10 min, and the final removal efficiency of CR was up to 96 @C NPs exhibit better performance for negative charged MO, which strongly suggests that the interaction between adsorbent and adsorbate is electrostatic. In summary, the different adsorption behavior together with the magnetic separation provide a simple and versatile strategy toward designing hybrid NPs for a variety of requirements in water pollution treatment.…”

“…The authors demonstrate the easy magnetic separation of Fe 3 O 4 @C after the adsorption of methylene blue (MB). Hao et al [19] studied the magnetic separation of Fe 2 O 3 @C nanoparticles after dye removal. They observed that the dye-loaded in iron oxide/carbon nanoparticles could be easily separated by placing a conventional laboratory magnet beside the glass bottle.…”

Journal of Advanced Chemical EngineeringLima et al., J Adv Chem Eng 2017, 7:1 DOI: 10.4172/2090 Volume AbstractCore-shell Fe 3 O 4 @C nanoparticles consist of a magnetic core and carbon coating, and exhibit high adsorptive capacity, easy magnetic separation and reusability. Due to these properties, core-shell Fe 3 O 4 @C nanoparticles have great potential application in adsorption, separation and wastewater treatment. Magnetic separation based on the super paramagnetic Fe 3 O 4 has received considerable attention and is widely used for the removal of dye, oil pharmaceuticals and metals from water due to its high efficiency and economic viability. Therefore, the main characteristics of the core-shell Fe 3 O 4 @C nanoparticles, the different types of synthesis, as well as the main applications for the removal of water pollutants were reviewed. In this brief review, an overview of the basic properties of the Fe 3 O 4 @C core-shell nanoparticles are given, and the most important and more frequently used methods for the synthesis of Fe 3 O 4 @C core-shell nanoparticles have been summarized along with the description of its adsorbent application potential.

“…To better understand the adsorption ability of the modied PP composite membrane, the adsorption amount of Congo red particles obtained in this work is compared with other materials (absorbents) reported in the literatures. [47][48][49][50][51][52][53][54] As shown in Fig. 12, the modied PP composite membrane exhibits the adsorption amount of about 500 mg g À1 , which is slightly lower than the 560 mg g À1 of carbon nanotubes (CNTs)/graphene aerogel but apparently higher than those of the other absorbents.…”

In this work, a graphene oxide (GO)-filled polypropylene (PP) adsorptive membrane was developed through an environmentally benign plasma-treatment technology. The PP/GO composite membrane was prepared through melt-compounding and subsequent compression molding processing.The composite membrane was further modified through the plasma treatment with allylamine as the monomer. The results showed that the modified composite membrane exhibited a high hydrophilicity, which is attributed to the introduction of a large number of nitrogen-containing and oxygen-containing groups. The plasma assisted surface modification technology was applied to the porous composite membrane that was prepared through uniaxial stretching processing. Although the porosity of the porous membrane gradually decreased with increasing discharge time during the plasma treatment, the modified porous membrane exhibited an excellent adsorption ability. When adsorbing the particles from the solution, the amount of adsorbed Congo-red particles increased with increasing discharge time. The adsorption mechanism of the treated porous membrane was then analyzed. This work provides an efficient method to apparently improve the hydrophilicity and adsorption ability of PP-based composite membrane which has great potential in the field of wastewater treatment.Through a plasma treatment, a PP-based composite membrane with a high hydrophilicity and an excellent adsorption ability was developed.
