Clean approach to synthesis of graphene like CuFe2O4@polysaccharide resin nanohybrid: Bifunctional compound for dye adsorption and bacterial capturing

Methylene blue removal from aqueous solutions using a biochar/gellan gum hydrogel composite: Effect of agitation mode on sorption kinetics

“…It is noteworthy that the degradation of organic compounds by the catalytic process may, in certain cases, produce even more hazardous compounds than the precursors [11,12]. Sorption represents an alternative strategy for the recovery of dyes from aqueous solutions, using low-cost bio-based sorbents [13,14], chitosan, and derivatives [15][16][17]. Nano-based materials [18], resins [19][20][21], and silica [22][23][24] have also been referenced for their efficiency in dye removal.…”

Study on the Adsorption of CuFe2O4-Loaded Corncob Biochar for Pb(II)

“…As a continuation of the last study, this study focuses on the use of spinel copper ferrite (CuFe 2 O 4 ) for producing a novel magnetic biochar composite for enhanced removal ability of the heavy metal ions from the aqueous solutions. To date, CuFe 2 O 4 and its derived composites have been extensively used for the abatement of various pollutants such as organic dyes [ 27 , 28 , 29 , 30 , 31 ], anions [ 31 , 32 , 33 , 34 ], arsenic [ 31 , 35 , 36 ], heavy metal ions, and organic toxicants [ 30 , 31 , 37 , 38 ], thus, implying that CuFe 2 O 4 exhibits optimal properties for environmental applications. Therefore, introducing CuFe 2 O 4 modifier into biochar may reach the expected requirements for adsorbents such as good magnetic separability, good adsorption capacity, eco-friendly character, and low budget.…”

Sunflower pollen-derived microcapsules adsorb light and bacteria for enhanced antimicrobial photothermal therapy

“…Physical adsorption is a straightforward method in which HSECs attach to S. aureus through various interactions, such as topological interactions, hydrogen bonding, and intermolecular π-π-stacking. 56,58,60,61 The rough surface of HSECs and the hairy structure of bacteria contribute to the topological interactions. Additionally, hydrogen bonding occurs between the hydroxyl groups of HSECs and the cell wall of S. aureus.…”
