Preparation of dialdehyde cellulose graftead graphene oxide composite and its adsorption behavior for heavy metals from aqueous solution

Recent Advances in Applications of Hybrid Graphene Materials for Metals Removal from Wastewater

“…Adsorbents based on combination of metal oxide and inorganics with graphene were synthesized via hydrothermal routes [30,62,65,66]. No strong correlation between the adsorbent surface area and the adsorption capacity of these composites can be made [53,59,67]. The most economic synthesis methods are those using fewer chemicals and production steps.…”

“…The potential for the regeneration of the lead loaded adsorbents has also attracted much attention and several studies have investigated the reusability of the sorbents after regeneration. These include: CoFe 2 O 4 -G, NiFe 2 O 4 -G, Fe 3 O 4 -GS, EDTA-mGO, EDTA-MCS/GO, DTPA/MGO, GOMCS-IL, and IT-PRGO, Mg−Al LDH / pRGO [67][68][69][70][71][72][73][74][75]. Most of these nanocomposites were reusable with Fe 3 O 4 -GS and EDTA-mGO maintained more than 80% of their original adsorption capacity [76,77].…”

Isolation and Characterization of Magnetic Oil Palm Empty Fruits Bunch Cellulose Nanofiber Composite as a Bio-Sorbent for Cu(II) and Cr(VI) Removal

“…Among these techniques, adsorption is considered a promising method for removing heavy metal from effluent because of its distinct advantages over other technologies, including easy to operate, cost-effective, and element trace metal ions [5,[12][13][14]. Various materials such as clay [12], activated carbon [13], chelating materials [14], and natural polymer [15] have been utilized as an adsorbent for the elimination of the heavy metals from industrial effluents. However, the low sorption efficiency of these adsorbents has limited their application in the adsorption of heavy metals [2,3].…”

“…There is increasing interest of utilizing biobased materials from the natural resources in various industrial and environmental applications due to the rapid depletion of global petrochemical-based resources and environmental pollution concern [15,17]. Among the various biobased materials, the plant cellulosic materials have attracted wide interest because of environmentally friendly nature, abundance availability, biodegradability and renewability [17,18].…”

Synthesis of a Novel CQDs‐GO‐Ag2S Composite and Study on the Adsorption of Methylene Blue

“…developed a magnetic nanocomposite adsorbent by combining nitrogen‐doped lemon juice‐derived carbon quantum dot and Fe 3 O 4 (Fe 3 O 4 @NCQDs NCS), which was used to remove methylene blue pollutants from aqueous solution and the system exhibited a good adsorption performance. In the attempt to remove Cu(II) and Pb(II) from aqueous solution, Yao et al . synthesized an adsorbent by grafting dialdehyde cellulose (DAC) on the GO template using triethylenetetramine as the crosslinking agent.…”
