“…Change in the NH 2 deformation initially at 1577 cm -1 in HA-NH 2 and CS, which shifted to 1560 cm -1 in the hybrids can also be associated to unreacted NH 3 + , offering adsorption sites for DS (Pratt et al, 2013;Shi et al, 2017).…”

“…The XRD patterns of chitosan presented two broad peaks at 2θ of 9.8° and 19.9°, which were assigned to hydrated regions and coexisting ordered and amorphous regions, respectively (Bayrak, Demirtaş, & Gümüşderelioğl, 2017;Shi et al, 2017). The crosslinking reaction promotes the interaction between the silylated HA and chitosan mediated by a bifunctional agent on the molecular scale to generate an inorganic-organic hybrid (Huang et al, 2011).…”

“…CS also interacts with inorganic matrices, resulting in composites with improved properties such as enhanced chemical stability (Chatterjee et al, 2018). Among inorganic matrices, calcium phosphates, such as hydroxyapatite, have been applied as good candidates to form new hybrids for environmental applications (Shi, Lv, Wu, & Hou, 2017). Hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 ) is used as an adsorbent due to its biocompatibility and its production in large scale by using green, economic and easy processes (Wang et al, 2017).…”

“…Consequently, it is urgent to explore economic and effective techniques for minimizing the dye contamination [11]. Research to date have shown that dye-laden effluents can be remediated by multiple approaches, including advance oxidation [12], membrane filtration [13,14], adsorption [15,16] and coagulation/flocculation [17], among others. Amongst these methods, adsorption has gained prominence in the decolourization of dye wastewater based on its simple design, easy operation and high efficiency [15,18,19].…”

A greener and sustainable pathway to the assembly of Fe, Cu -based adsorbent is described using Virginia creeper () leaf extracts in presence of oxalic acid which avoids the use of toxic chemicals. Characterization of the synthesized mixed Fe, Cu oxides are carried out by SEM, TEM, XRD, FT-IR, XPS, and BET techniques; SEM and TEM results disclosed particle size ranging from 160 nm to 1 μm in presence of varying oxalic acid amounts of 0 and 0.1 mol/L. The X-ray photoelectron spectroscopy studies revealed that the sample comprised of Fe, Cu-based hybrid oxides and oxalates. The ensuing results from altered operational parameters namely initial pH, initial malachite green (MG) concentration, the sample dosage and the reaction temperature suggest that the MG adsorption capacity of synthesized materials could be well structured by simply varying the amount of oxalic acid. The optimal sample (S sample) has a remarkably high maximum adsorptive capacity (~1399 mg/g) for aqueous MG removal at 303 K and natural pH (~ 6.58), which is superior to recently documented sorbents. The results demonstrate that the adsorption is spontaneous (i.e., ∆G < 0) via an endothermic process wherein the synthesized adsorbent displayed excellent characteristics: 1) maintained a high adsorption capacity under a wide range of pH conditions; 2) remained chemically stable under ambient storage environments to allow for extended stowage; and 3) portrayed high reusability with no waning effect after 4 adsorption/desorption cycles.
