“…Furthermore, the compatibility of the adsorption data with the pseudo‐second‐order kinetic model confirmed the presence and involvement of electrostatic interactions in the process of the adsorption of the dye molecules onto the biosorbent. It was concluded that RO16 dye adsorption by the C‐TPP‐PEE biosorbent was significantly affected by both the solution pH and functional groups on the biosorbent surface due to electrostatic attraction and hydrogen bonding 43, 44.…”

The green composite chitosan/tripolyphosphate/mushroom (C-TPP-PEE) was synthesized and evaluated for its adsorption performance of the dye Reactive Orange 16 (RO16), by using the batch technique. Fourier-transform infrared spectroscopy, thermogravimetric analysis, and field emission scanning electron microscopy were employed to characterize the C-TPP-PEE. The maximum adsorption capacity of the RO16 dye for batch adsorption was determined as 736 mg g -1 . The experimental kinetic data at equilibrium was found to be best fitted to the pseudo-second-order kinetic model. The results showed that the adsorption isotherm was best correlated to the Langmuir model. The thermodynamic data indicated that the adsorption process was spontaneous, favorable, and endothermic.

“…Glutaraldehyde was also used as a cross-linking reagent (Scheme 2b) to fabricate magnetic chitosan-coated poly (acryloyloxyethyltrimethyl ammonium chloride) to form Fe 3 O 4 -CS/PDAC 59 via a free radical polymerization reaction. 71 The Fe 3 O 4 -CS/PDAC displayed a rough surface (Figure 2d-f) with a large surface area, chitosan mass content of 37.1%, and better saturation magnetization. Thus, glutaraldehyde reagent types possess unique characteristics such as utilizing Michael-type addition reaction or aldol condensation and cross-link proteins which leads to the production of a wide range of conjugates.…”

“…Thus, glutaraldehyde reagent types possess unique characteristics such as utilizing Michael-type addition reaction or aldol condensation and cross-link proteins which leads to the production of a wide range of conjugates. 72 Besides, a different cross-linking reagent, namely green tea and an alkaline epichlorohydrin solution, were 71 used to prepare magnetic chitosan particles (MCPs) from shrimp shells and steel slag and chitosan gels, respectively. 73 The MCPs possessed high magnetization as they can be easily recovered using a magnet.…”

Magnetic chitosan has received considerable attention over the decades due to its low cost, biodegradability, green sources, magnetic intensity. In this review, we reviewed the preparation methods of magnetic chitosan using co-precipitation, cross-linking and electrochemical. Therein cross-linking methodologies involved in the reaction of amino groups are facile to introduce additional reaction groups and improve anti-swelling of chitosan layers, mostly in an acidic environment. Besides, we focused on the applications of magnetic chitosan in various fields such as wastewater treatment, for example, removal of heavy metal ions, organic/inorganic dyes, fluorides, and pesticides. Moreover, magnetic chitosan also reveals great potential application in the field of medical, pharmaceutical, food and electronic screening. Above all, magnetic chitosan is economically and operationally beneficial as it can be easily separated and controlled with an external magnetic field and can be modified to maximize its functions.

“…In a similar work. chitosan mixed with prefabricated 50 nm-diameter Fe 3 O 4 nanoparticles (average size, 50 nm) was crosslinked and polymerized with poly(acryloyloxyethyltrimethyl ammonium chloride) (PDAC) in order to form magnetic beads with a size range between 100 and 200 µm by Sarfaraz et al [153] (Figure 8) who then tested them for the removal of inorganic chromium (VI) ions and organic sunset yellow dye. The composites showed maximum adsorption capacities for chromium (VI) ions and sunset yellow dyes of 163.93 mg•g −1 and 769.23 mg•g −1 , respectively with moderately better performance at lower pH and a high degree of reusability for the removal of both contaminants.…”

Water resources are of extreme importance for both human society and the environment. However, human activity has increasingly resulted in the contamination of these resources with a wide range of materials that can prevent their use. Nanomaterials provide a possible means to reduce this contamination, but their removal from water after use may be difficult. The addition of a magnetic character to nanomaterials makes their retrieval after use much easier. The following review comprises a short survey of the most recent reports in this field. It comprises five sections, an introduction into the theme, reports on single magnetic nanoparticles, magnetic nanocomposites containing two of more nanomaterials, magnetic nanocomposites containing material of a biologic origin and finally, observations about the reported research with a view to future developments. This review should provide a snapshot of developments in what is a vibrant and fast-moving area of research.
