“…The values of thermodynamic parameters obtained from equation (15) and van't Hoff plot (figure S6) for adsorption of CR and IC on CHCA are listed in table 6. The negative values of ΔG 0 at all temperatures for both the dyes confirms the feasibility and spontaneous nature of the adsorption process.…”

“…Despite several techniques available, adsorption is considered most promising due to its extensive applicability, ease of operation and cost-effectiveness. Adsorption technique is not only efficient for the removal of soluble and insoluble organic pollutants, it is also an environmentally benign process owing to the non-generation of hazardous by-products [13][14][15]. Activated carbon, because of its textural properties, larger surface area, pore volume and pore structure, is the widely used conventional adsorbent material for the removal of pollutants from aqueous systems [16].…”

Solution combustion synthesis of calcium aluminate (CaAl 2 O 4 ) nanocomposite using coffee husk extract and its adsorption capacity for removal of Congo red (CR) and Indigo carmine (IC) are reported. Physiochemical properties of adsorbent were studied by PXRD, SEM, TEM and point of zero charge. Batch adsorption studies were conducted to study the effect of adsorbent dosage, pH, contact time, initial dye concentration and temperature on adsorption efficiency of coffee husk derived calcium aluminate nanocomposite (CHCA). Among the isotherms used, Langmuir model explained best the equilibrium data and the maximum monolayer adsorption capacity was found to be 377 and 135 mg/g for CR and IC, respectively. Mass transfer analysis indicated adsorptive removal of dyes was controlled by both external and internal diffusion. Pseudo-first-order model fitted best with experimental kinetic data and adsorption efficiency increased with an increase in the initial bulk concentration of CR and IC. Thermodynamic analysis indicated that adsorption of CR and IC on CHCA is feasible, spontaneous and exothermic in nature. The magnitude of enthalpy and heat of adsorption suggested that the adsorption is physical in nature. The present study explores the potential of coffee husk extract, an agro-based bio-waste, as a novel and eco-friendly fuel in the synthesis of CHCA and the synthesised nanocomposite as a potential adsorbent for the removal of synthetic dyes.

“…They have a large surface area, high magnetic properties, and a high adsorption rate and efficiency [22,23]. Magnetite (Fe 3 O 4 ) nanoparticles [23], ferrite (Fe 2 O 3 ) nanoparticles [24], magnetite/carbon nanocomposite iron nanoparticles [25], and cobalt-zinc ferrite nanoadsorbents [26] were used to remove and purify the wastewater. Kinetic studies of them for dye adsorption fit the second-order kinetic model and Langmuir isotherm [23,25] well.…”

A polypyrrole-chitosan-calcium ferrite nanocomposite was prepared using the electrodeposition method. The prepared layer was characterized by using Fourier transform infrared spectroscopy, the X-ray diffraction technique, and field emission electron microscopy. The thickness of the thin layers was in the range of 2.8 nm to 59.5 nm, and the refractive index of the composite layer was in the range of 1.66131+0.156i to 1.62734+0.167i. Detection and removal of cationic and anionic dyes, such as methylene blue and methylene orange, are subject of great interest for protecting environmental water. The layer composite was used to detect methylene orange and methylene blue using the surface plasmon resonance technique. Consequently, the polypyrrole-chitosan-calcium-ferrite composite layer interacted with the anionic and cationic dyes. The resonance angle shift for the detection of the cationic dye was larger than the resonance angle shift for the anionic dye. The sensor limit was achieved from a sensogram at about 0.01 ppm.

“…The familiar technique is the adsorption process which has become one of the most effective means for transferring the solute from the liquid phase to the solid phase of a sorbent [8][9][10][11][12][13]. Adsorption can be achieved by using different material especially the activated carbon which is a very useful and effective technique in the remediation of wastewater contaminated with organic compounds [14][15][16][17]. In this regard, the previous literature was directed towards the adsorption of benzaldehyde using traditional sorbents such as activated carbon cloth [18], granular activated carbon [3], natural clay and Faujasite-Y type zeolite [19].…”

Iron slag is a byproduct generated in huge quantities from recycled remnants of iron and steel factories; therefore, the possibility of using this waste in the removal of benzaldehyde from contaminated water offers an excellent topic in sustainability field. Results reveal that the removal efficiency was equal to 85% for the interaction of slag and water contaminated with benzaldehyde at the best operational conditions of 0.3 g/100 mL, 6, 180 min, and 250 rpm for the sorbent dosage, initial pH, agitation time, and speed, respectively with 300 mg/L initial concentration. The maximum uptake capacity of iron slag was 118.25 mg/g which was calculated by the Langmuir model. Physical sorption may be the major mechanism for the removal of benzaldehyde onto iron slag based on the analysis of isotherm and kinetic sorption data and thermodynamically, the process was spontaneous and endothermic. Finally, the X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD), Fourier transform infrared (FT-IR), scanning electron microscope (SEM) and energy-dispersive spectroscope (EDS) tests for reactive material certified that the dissolution of calcium oxide can enhance the removal of benzaldehyde by the formation of bridge cations.
