Magnetic EDTA-modified chitosan/SiO2/Fe3O4 adsorbent: Preparation, characterization, and application in heavy metal adsorption

Neuro-fuzzy modeling to adsorptive performance of magnetic chitosan nanocomposite

“…For instance, several magnetic chitosan composites such as chitosan/Fe 3 O 4 [14][15][16], chitosan/Al 2 O 3 / Fe 3 O 4 [17,18], polyoxometalate-grafted chitosan/Fe 3 O 4 [19] and magnetic graphene/chitosan [8] have been reported as efficient adsorbent composites for the removal of organic pollutants. Also, Zhao et al [15,20], Ayati et al [21], Ren et al [22] and Yang et al [23] used the magnetic chitosan composites for the adsorption of different metal ions adsorption as well as Reddy et al [24] and Vakili et al [10] who studied the adsorption performance of magnetic chitosan composites for metal and dyes removal from aqueous solutions. The works in the literature have been mostly focused on the synthesis and adsorption mechanism and highlighted the effective parameters on the adsorption capacity of these composites.…”

Modification of Silica Coated on Iron Sand Magnetic Material with Chitosan for Adsorption of Au(III)

“…In the hybridization of silica and chitosan, chitosan solution which used referred to the previous research with the concentration in a range of 1-3% [13,[22][23].This is related to the viscosity of chitosan solution, where the more viscous solution, the mobility of molecules decreases. In this research, a preliminary study of chitosan with variation of 1-3% (weight/volume) was conducted to obtain optimum composition of chitosan solution used for the next stage.…”
