“…In terms of simplicity of usage and design, flexibility, cheapness, insensitivity to toxic pollutants, and safety, the adsorption technique for dye removal from wastewater effluent represents a wide area of interest 12 – 15 . In this regard, nanocomposite materials inter in a wide range of applications in numerous areas due to remarkable catalytic activity, high specific surface area high reducibility, and their chemical stability 16 – 19 . For wastewater treatment especially dyes removal, metal oxides, and metal oxides nanocomposite showed a high rate of dyes degradation and/or adsorption 20 – 26 .…”

A comprehensive study that combined both experimental and computational experiments was performed to evaluate the usage of organo-metal oxide nanocomposite for the elimination of disperse red 60 dye (DR) from aqueous solutions. Chitosan was modified by Schiff base to form nanoneedles chitosan-4-chloroacetophenone derivative. The derivatives were then impregnated with CeO2–CuO–Fe2O3 or CeO2–CuO–Al2O3 metal oxides to prepare a novel quarternary organo-metal oxide nanocomposite. The novel nanocomposite, chitosan-4-chloroacetophenone/CeO2–CuO–Fe2O3 (CF) and chitosan-4-chloroacetophenone/CeO2–CuO–Al2O3 (CA) are cheap and effective nano adsorbents that can be used for the uptake of DR from aqueous solution. The CF and CA nano-composites were characterized using different techniques. Moreover, the effect of adsorption parameters (initial DR concentration, time of contact, pH, temperature, and adsorbent mass) as well as CA and CF reusability tests were performed. Langmuir adsorption isotherm and pseudo-second-order kinetics models were best fitted with the adsorption process. The maximum amount of DR adsorbed was 100 mg/g on CF and CA at pH 2 and 4, respectively with a physical spontaneous, and exothermic adsorption process. Monte Carlo (MC) simulation studies indicated the adsorption of DR molecule on the CF and CA surfaces following a parallel mode in most of all studied configurations, confirming the strong interactions between the DR and surfaces atoms of CF and CA. The molecular structure analysis of DR dye adsorbed on the surface of CF and CA indicated that the adsorption process related to Van der Waals dispersion force. Consequently, this helps to trap DR dye molecules on the surface of CF and CA (i.e., physical adsorption), which supports our experimental results.

“…Utilising XRD-Bruker Co. Germany, D8 Advanced, Cu target, 1.54 Å, and radiation operated at 40 kV and 40 mA, 2θ=3°to 70°, step 0.020°and step time of 0.4s, the phase composition was determined. The crystallite size (D) was calculated using the Scherrer formula l = D K L X cos 2 [21,22], where λ is the wavelength of the incident x-rays, L is the linear dimension of the particle, X/2 is the Bragg angle, and K=the numerical constant equals 0.93. FTIR was used to determine the various elemental constitution groups in the range of 400−4000 cm -1 using equipment (FTIR-ATR Brucker Vertex 80 V).…”

Hydroxyapatite (HA) is a biomaterial that has been widely studied for uses such as bone grafting and tissue engineering. Pure and hydroxyapatite nanoparticles with cationic (Na, Ti, and Li) as well as anionic ( CO 3 2 − and Si4+) substitutions were synthesised using a wet chemical precipitation method followed by freeze-drying and investigated for their cytotoxicity effect. Inductively coupled plasma (ICP), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy were used to characterise the produced powders. The production of the HA phase was confirmed in all synthesised HA samples. MTT (3-(4.5-dimethylthiazol-2-yl)−2.5-diphenyl tetrazolium bromide) assay was performed using the BJ1 cell line of human normal fibroblasts to investigate the cytotoxicity of the synthesised HA samples. The cytotoxicity test showed that the HA samples were biocompatible, with the greatest results coming from Li-substituted (LiHA2) and Na-substituted (NaHA) hydroxyapatite.

Kiln rollers, which are widely used in ceramic tiles production, are usually subjected to surface grinding to remove the contaminations. The resulted fine powder is considered useless waste and a hazardous source of environmental pollution particularly as it contains health‐threatening fine free silica. In the present paper, the grind waste from kiln rollers was reused as raw material in the fabrication of nanofiltration ceramic membrane. The samples of produced ceramic membranes were formed into disks by adding 15% (by weight) organic binder solution with 2% concentration, then pressed at 35 MPa, dried and fired at temperatures range from 1100°C to 1300°C for 1 hour soaking time. It was found that the best firing temperature to produce nanofiltration ceramic membrane is 1250°C, where the ceramic membrane provides high removal of turbidity and high monovalent, divalent, and trivalent salts separation percentage.
