This study reports a novel magnetic nanoadsorbent prepared from magnetite (Fe3O4) as the magnetic core, activated carbon from coal fly ash and an ionic liquid (1-methyl-3-ethylimidazolium chloride). The magnetic nanoadsorbent was synthesized via co-precipitation and characterized by FTIR, XRD, TEM, EDS and BET surface area anal. Batch adsorption studies on cadmium (Cd2+) and lead (Pb2+) solutions such as effect of pH, contact time and adsorbent dosage were carried out. The data was analyzed using the Langmuir and Freundlich models. The results revealed that the optimal adsorption conditions for both metal ions on synthesized nanoadsorbent were pH 6, 200 min, adsorbent dosage of 1.5 g/L, initial ion concentration of 10 ppm and a temperature of 25°C. The data obtained in the adsorption of Cd2+ and Pb2+ best fitted the Freundlich isotherm, with R2 values of 0.998 and 0.995, resp. Thermodn. and kinetic studies suggested that adsorption of both metal ions on the IL-AC-Fe3O4 nanocomposite followed the pseudo first order model. The synthesized nanoadsorbent (IL-AC-Fe3O4) exhibits good adsorption properties and has great potential in a water treatment technol. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .
1-Ethyl-3-methyl-1H-imidazol-3-ium chloride(cas: 65039-09-0) is an imidazolium chloride ionic liquid that can be used as:a starting material for the preparation of 1-ethyl-3-methylimidazolium chloride/tetrafluoroborate (EMI.Cl.BF4) molten salt for electrochemical studies; a solvent as well as catalyst for the depolymerization of oak wood lignin.Electric Literature of C6H11ClN2
