A new modified magnetic Graphene Oxide with Chitosan and Cysteine wassynthesized for removing Pb2+ ions from aqueous solution. The properties of thisadsorbent were characterized by Field Emission Scanning Electron Microscopy (FESEM),Vibrating Sample Magnetometer (VSM) and Energy Dispersive Analysis Systemof X-ray (EDAX). Physicochemical parameters such as effect of pH, c...

Background: Phosphorus is an indispensable element for the growth of animals and plants. There are several environmental problems related to phosphate; therefore, the technical and economic methods of removing phosphate are of great importance. This study evaluated the efficiency of polyaniline/Ni0.5Zn0.5Fe2O4 magnetic nanocomposite in removing phosphate from aqueous environments. Methods: The...

Functionalized magnetic adsorbents (FMAs) were synthesized by a facile and surfactant-free one-pot solvothermal approach, using iron(III) chloride hexahydrate as the precursor, ethylene glycol as the reducing agent, ammonium acetate, and EDTA-2Na as an electrostatic stabilization agent. The self-assembly process of the functionalized magnetic adsorbents has been investigated and a plausible mec...

An efficient and simple magnetic solid phase extraction based on the use of CoFe3O4 nanoparticles grafted multi-walled carbon nanotubes (MWCNTs) as adsorbent coupled with surfactant enhanced spectrofluorimetric detection...

This work investigates the potential of magnetic Fe3O4 nanoparticles as an adsorbent for separation and preconcentration of trace amounts of mefenamic acid in aquatic and biological samples, prior to spectrophotometric determination. The magnetic iron oxide nanoparticles (MIONs) were synthesized by mixing of ferrous and ferric chlorides. The possible parameters affecting the enrichment were opt...

In the present study, removal of dibenzothiophene (DBT) from model oil (n-hexane) was investigated using magnetic activated carbon (MAC) nano-composite adsorbent. The synthesized nano-composite was characterized by FT-IR, FE-SEM, BET and VSM techniques. The MAC nano-composite exhibited a nearly superparamagnetic property with a saturation magnetization (Ms) of 29.2 emu g-1...

Introduction: Anthracene is one of the chemical and persistent pollutants released into the environment and the food chain causing irreparable damage to the immune system. This study aimed at removing anthracene from aqueous solutions using modified magnetic nanoparticles.   Materials & Methods: Initially, Fe3O4 nanoparticles were synthesized with silicon dioxide shell and then modified with ...

With increasing awareness of reduction of energy and CO2 footprint, more waste is considered recyclable for generating value-added products. Here we reported the negatively-valued iron mud, a waste from groundwater treatment plant, was successfully converted into magnetic adsorbent. Comparing with the conventional calcination method under the high temperature and pressure, the synthesis of the ...
