“…Among the various materials used for chromium removal, nanoparticles have been the most common, either using just the core nanoparticles [9,[40][41][42][43][44][45][46], nanoparticles with functionalization [35,[47][48][49], or modified nanoparticles incorporated on substrates [36,50]. Other type of materials have been used, such as nanocomposites [37,51,52], nanofibers [38] and carbon nanotubes [39].…”

Current environmental policies aim to reduce the levels of toxic substances in aquatic ecosystems and to promote the water reuse after appropriate treatment of wastewater.Chromium is a hazard element present in effluents of various industries that should be reduced to achieve the objectives of those policies. Most of the results reported in the literature concern the use of nanomaterials for chromium sorption dissolved either in synthetic or mono-elemental spiked solutions. The present work reviews the results of research undertaken in the last decade on the application of various nanomaterials to decrease chromium concentrations in contaminated waters. Major factors influencing the removal efficiency were examined. Because most of the published studies are based on simple experiments with deionised water and mono contamination further studies are suggested focused on effects of natural and artificial chelators, interferences of other trace elements competing with chromium sorption, reduction the sorbent mass per water volume.

“…Only a few studies addressed the treatment of contaminated waters as real samples, such as groundwater, effluents or wastewater [41,46,48,55,56]. Chen et al [57] have simulated natural waters by testing solutions of different complexity, deionized distilled water, tap water, mountain stream water and river water.…”

“…The found values for the specific surface area, total pore volume and average pore size were 116 m 2 g -1 , 0.282 cm 3 g -1 and 8.90 nm, respectively. Kalam et al 36 found a surface area value of 76 m 2 g -1 for the CoFe 2 O 4 particles prepared by modified solvothermal process with polysaccharide, whereas Srivastava et al 37 found a value of 41.3 m 2 g -1 through the modified co-precipitation method. CoFe 2 O 4 particles prepared by sol-gel 38 and hydrothermal 39 methods presented surface area values of 10 m 2 g -1 and 85 m 2 g -1 , respectively.…”

In this work, cobalt ferrite (CoFe 2 O 4) was synthesized by solvothermal route for application as a catalyst in the ozonation reaction for the decolorization and mineralization of melanoidin from aqueous solution. The structural properties of CoFe 2 O 4 sample were investigated by X-ray diffraction (XRD), nitrogen adsorption-desorption isotherms, Fourier-transform infrared spectroscopy (FTIR), particlesize distribution, scanning electron microscopy (SEM) and X-ray dispersive energy spectroscopy (EDS). Single-phase CoFe 2 O 4 particles with a predominantly mesoporous structure containing a high specific surface area were obtained. Results showed that the CoFe 2 O 4-catalyzed ozonation reaction has higher activity for the decolorization and mineralization of melanoidin when compared with the ozonation reaction without the presence of catalyst. Therefore, this material can be very promising for the application in catalytic ozonation systems for the melanoidin removal from liquid effluents.

“…It has been determined in previous studies that CoFe 2 O 4 nanoparticles are heavy metal removed. For example, Srivastava et al [9] reported that CoFe 2 O 4 nanoparticles removed Cr (VI) from waste water. In this study, it was determined that CoFe 2 O 4 nanoparticle synthesized by bark extract of A.hippocastanum fruits removed 78.5% of crude oil from water.…”

Magnetic nanoparticles are widely used in areas such as biosensors, data storage devices, waste water treatment and biomedicine due to their biocompatibility and low toxicity. In this study, biosynthesis of the CoFe2O4 nanoparticle (NP) was carried out using the bark extract of Aesculus hippocastanum plant as a reducing and capping agent. Synthesized NPs were char-acterized by ultraviolet-visible spectrophotometer (Uv-Vis.), Dynamic Light Scattering (DLS), zeta load, X-Ray Dust Diffraction (XRD), Fourier Transformed Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy, Raman, BET, and Thermogravimetric Thermal Analysis (TGA). The Lethal dose value (LD50) and the crude oil removal efficiency were examined. The characteristic light absorption of the CoFe2O4NP has been measured at 330 nm, surface charge of +14.4 mV, mean size of 75 nm and effective diameter of 432 nm. The XRD analy-sis revealed that the particle structure was in the cubic spinel structure with functional groups bound by FT-IR analysis and Raman data. It has been noted that the CoFe2O4NP, which was synthesized by biological method, can remove a 78.5% of the crude oil from the contaminat-ed water. It has been determined that the NP’s have a low toxic effect on D. magna (LD50= 728.267 ppm). In this study, it has been suggested that the CoFe2O4 NP with A. hippocasta-num bark extract could be synthesized by a cheap, relatively easy and environmentally friendly method which used for purification of contaminated water bodies.
