“…However, as mentioned above, the main application of iron-based systems still remains in the field of adsorption. Iron-based nanoparticles, in fact, can be functionalized very easily to tune their removal efficiency towards several contaminants ranging from organic molecules to metals and ions [1,[21][22][23][24][25][26][27][28][29][30][31][32][33][34]40,41].…”

The Lab4treat experience has been developed to demonstrate the use of magnetic materials in environmental applications. It was projected in the frame of the European project Mat4Treat, and it was tested several times in front of different audiences ranging from school students to the general public in training and/or divulgation events. The experience lends itself to discuss several aspects of actuality, physics and chemistry, which can be explained by modulating the discussion depth level, in order to meet the interests of younger or more experienced people and expand their knowledge. The topic is relevant, dealing with the recycling of urban waste and water depollution. The paper is placed within the field of water treatment for contaminant removal; therefore, a rich collection of recent (and less recent) papers dealing with magnetic materials and environmental issues is described in the Introduction section. In addition, the paper contains a detailed description of the experiment and a list of the possible topics which can be developed during the activity. The experimental approach makes the comprehension of scientific phenomena effective, and, from this perspective, the paper can be considered to be an example of interactive teaching.

“…At a magnification of 2480, agglomeration clusters of small particle dispositions were seen evidently on its topography for both copper and cadmium, shown in Exhibit 16(b) and (c), respectively. Thus, better adsorption behavior was predicted for the prepared adsorbents which denote clear deposition and appearance of Cu and Cd (II) metals on its topographical structure (Gupta & Ahmaruzzaman, 2021). A similar SEM pattern of the ‐synthesized Cu‐MOF adsorbents with irregular clusters of spherical particles fused were noticed at a magnification of 10,000.…”

Pollution of water, air, and soil by industrial effluents is a major problem nowadays. A variety of contaminants are too responsible for changing the physicochemical properties of the receiving body. There are practical treatment solutions available to clean up contaminants from various resources. The term "adsorption" refers to one of them.The purpose of the research work is to remove heavy metals from industrial effluent.Mixed adsorbents prepared from activated charcoal and bone charcoals were used to remove the copper and cadmium ions. The experiment carried out in a batch operation and modeling of these data for intraparticle diffusion and thermodynamic calculations were reported in this research work. At optimum operating condition pH 6; metal ion concentration 50 mg/L; dose 5 g/L; agitation 180 rpm and temperature 40 • C maximum 99.41% copper ions and 88.12% cadmium ion removal was achieved. Cadmium ions were well fitted in the thermodynamic model compared to copper ions, as demonstrated by the higher correlation coefficient R 2 (0.9824) value. Intra particle diffusion demonstrated that film diffusion was a rate-limiting step at the start of the reaction, while microporous intraparticle diffusion was the rate-determining phase later on. A Fourier transformation infrared spectroscopy, X-ray diffraction, and scanning electron micrography analysis confirmed the suitability of mixed adsorbents for the removal of cadmium and copper metal ions.

Cobalt mullite adsorbent for the robust adsorption performance towards Victoria Blue (VB) and Metanil Yellow (MY) is fabricated by the sol-gel method at room temperature using dipropylamine as a structuredirecting agent. The synthesized adsorbent is characterized by XRD, FT-IR and HRTEM. From these analyses, it is found that dipropylamine binds with the alumina and cobalt oxide which makes it into tetrahedral to octahedral form. This interaction causes the formation of cobalt mullite. It is observed that trigonal alumina and orthorhombic cobalt mullite are interlinked to form a hybrid network. The special feature of adopting this adsorbent for the adsorption of VB and MY is that it has a large amount of Brønsted acid site because of the octahedral coordination of Al and Co. The large availability of acid sites HighlightsCobalt Mullite is successfully fabricated by sol-gel method at room temperature.Aluminosilicate has tetrahedral framework, but introduction of Co 2+ into it make a hybrid network of tetrahedral and octahedral resulted in the formation of cobalt mullite in the framework.The hybrid framework generate more acidity which aid faster adsorption rate with higher adsorption capacity of VB and MY.
