Magnetic chicken bone-based biochar (MCBB) was successfully prepared and efficiently adsorbed rhodamine-B (RB) dye and tetracycline (TC) in multi-component systems. The magnetisation value, surface area, and pHpzc of the MCBB were found to be 66.5 emu/g, 328 m2/g, and 8.3, respectively. RB has higher saturation capacity (96.5 mg/g) and occupies more active sites on MCBB, thus limiting the ...
The kinetic data could be described by an intra-particle diffusion model, which indicated that the porosity of the sorbent strongly influenced the rate of sorption. The analysis of the equilibrium sorption data revealed that ionic strength and temperature did not play any significant role in the metaldehyde uptake. The sorption ...
The synthetized materials were characterized by X-ray diffraction, scanning electron microscopy, Brunauer–Emmett–Teller analysis, Fourier transform infra-red spectroscopy and thermogravimetric/differential thermal analysis. The sorption kinetic data fitted a pseudo-second-order model. The adsorbed amounts of the calcined material were much larger ...
The applicability of the kinetics models and the characteristics of the bed (sorption capacity, breakthrough curve, depth of the adsorption zone) were taken into account. ...
The surface properties of the obtained ACs were characterized via thermal analysis, N2 isothermal sorption, scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and Boehm titration. ...
Indion 225 and Dueolite C 20 cation-exchange resins through batch and column mode for the recovery of Ni (II), which showed a remarkable increase in sorption capacity. On the basis of isotherm analysis, more efficient adsorbent is chosen for column mode adsorption studies. ...
The preparation of a nanocrystalline hybrid anionic surfactant-akaganeite (denoted as Akh) as an innovative sorbent, the investigation of its surface properties and the evaluation of its ability to remove cations from aqueous solutions were studied in the present paper. The nanocrystalline hybrid anionic surfactant-akaganeite was prepared in the laboratory using FeCl3 as precursor and an anionic ...
In this study, the influence of parametric values on the risk of steel corrosion in concrete was quantitatively calculated in terms of the sensitivity to service life of concrete structures subjected chloride attack. Prior to the analysis, a thorough literature review on the chloride threshold level (CTL) for steel corrosion and the rate of chloride transport was performed to ...
The regeneration ability and decay of the limestone samples were investigated through sorption-calcination cycles in a thermogravimetric analyser operated at ambient pressure. The effects of the sorption time (3, 8 and 30 min), reaction temperature (750°C and 850°C) and particle size (38-53, 150-250 and 500-800 μm) on the sorbent performance were examined. ...
The initial and exhausted adsorbents were characterised using sorption of nitrogen, thermal analysis, and XRF, XRD and surface pH measurements. ...
Three levels of hydrated TiO2 particles size distributions have been detected as a result of SEM and STM analysis of the composites. Quantum-chemical simulation of titanium salts polymerisation processes was carried out. Analysis of sorption properties of titania composite materials has revealed that their microelements selectivity changes ...
