“…The calcined marble exhibited an adsorption capacity of 93 and about 95 mg/g for lead ions and acid red dye, respectively at 20C and pH 6 after 240 min. it indecates that the sorption capacity was good with comparing to literature (98 mg/g and 14 mg/g for Acid Red dye and lead ions) (Abbad and Alakhras, 2020;Rakhym et al, 2020).…”

The marble dust as a harmful industrial waste of marble fabrication was evaluated as aneconomical and efficient green adsorbent for Acid Red-1 dye and lead ions. The XRD, XRF, particle size, surface area and zeta-potential measurements were used to characterize the marble dust. The removal efficiency was optimized by studying several parameters such as pH, temperature, contact time, adsorbent dose and initial concentration. The optimum removal was achieved at pH 6, 20C after 60 min in the presence of 2.5g/L marble dust. The rates of adsorption were found to follow the pseudo-second-order model. The results showed better fitting to Freundlich isotherm. The thermodynamic studies revealed that the adsorption process is spontaneous, exothermic and favorable at low temperature. The free energy (∆G°), enthalpy (∆H°), and entropy (∆S°) changes were calculated to predict the nature of adsorption.The removal efficiency was improved by calcination of the marble at 700C. Application for textilewastewater showed high removal efficiency up to 99.9%of inorganic and organic pollutants. The product of treatment was used in the concrete and bricks manufactured, so there is nogeneration of second-order pollutants.

Synthesis, characterization, Pb(II) adsorption, recovery, preconcentration and reusability of different nanoadsorbents were investigated in detail. With green synthesis, silver, iron oxide and iron copper nanoparticles (AgNPs, Fe3O4NPs and Fe/CuNPs) were synthesized and modified with chitosan and alginate natural polymers to form nanocomposite beads (Fe3O4‐CS, Fe3O4−AT, Fe/Cu−CS and Fe/Cu−AT). When the adsorption efficiencies of the seven synthesized nanoadsorbents from the aqueous medium were compared, it was seen that the magnetic bimetallic Fe/Cu−CS beads provided the highest adsorption with 100 % efficiency for Pb(II). The adsorption mechanism, effects of temperature, initial lead ion concentration and pH of the solution on the Pb(II) adsorption capacity of Fe/Cu−CS beads were investigated. The recovery studies have shown that Fe/Cu−CS beads have good adsorption/desorption performance around 90 % of desorption was achieved with 5 mM HNO3. These results show that Fe/Cu−CS beads have potential to be a promising material for adsorption, preconcentration and desorption of Pb(II) from aqueous solution.

“…Kaolinite [33,34], montmorillonite [35,36], vermiculite [37] and bentonite [38][39] are some of the natural clays which were used as adsorbents for the separation and detection of different metal ions. In the literature, it was reported that chamotte clay was used for the palm kernel biodiesel purification [40] and adsorption of lead(II) [41]. However, to the best of my knowledge, a method based on the usage of chamotte clay for separation, preconcentration and determination of aluminium has not been proposed yet.…”

The adsorption behavior of aluminium ions on chamotte clay has been studied in this study. Chamotte clay has been used for the first time for determination of trace levels of aluminium in aqueous solutions. Quantitative adsorption and recovery of aluminium were both rapid and reached an equilibrium in 30 minutes. Aluminium was detected based on the formation of the highly fluorescent Al(III)-morin complex. Two linear calibration graphs were obtained in the range of 0.5-10 µg L-1 and 10-100 µg L-1 with the detection limits of 0.12 µg L-1 and 1.12 µg L-1, respectively. Chamotte clay was characterized by scanning electron microscope coupled with energy-dispersive X-ray spectroscopy, energy dispersive X-ray fluorescence and X-ray photoelectron spectroscopy techniques. Different isotherm models were evaluated and the results showed that the adsorption study was fitted to Freundlich isotherm and a favorable and multilayer adsorption of aluminium was occurred on the heterogeneous surface of the chamotte clay. Thermodynamic and kinetic parameters of aluminium adsorption were also investigated. Various experimental parameters were optimized and the method has been applied to tap and bottled drinking water samples and quantitative recoveries were obtained. The results demonstrated that the chamotte clay, as a natural clay, was expected to be a promising adsorbent for the determination and preconcentration of the trace levels of analyte in real samples.
