“…The main indication of hydroxyapatite is the strong broad band at~1040 cm −1 , which is associated to the asymmetric stretching vibration mode of PO 4 group [26]. Also, the bands at 604, 567 and 465 cm −1 correspond to P-O mode vibration of the PO 4 group [48,49]. The peak at 1385 is assigned to the vibration of the carbonate group [26,48].…”

“…Rhim et al prepared sodium carboxymethyl cellulose/cotton linter cellulose nano-fibril (CMC/CNF) composite films with good mechanical properties due to the high compatibility between CNF and CMC [19]. Azzaoui et al manuficated hydroxyapatite/ hydroxyethyl (HAp/HECA) inorganic-organic composite films which showed good thermal stability and miscibility due to the strong interaction between HAp and HECA [20]. It was also illustrated that the interaction between composites has a direct impact on the compatibility and the improvement of performance.…”

Novel liquid bio-composites were successfully prepared by blending the N-methyl diethanolamine (N-MDEA) modified poly (butylene succinate) (N-PBS) and carboxy-methylated cellulose (CMC) or hydroxyl-ethyl cellulose (HEC) in solution. In order to reveal the interaction mechanism between N-PBS and cellulose derivatives, the mixing energy and interaction parameter of (N-PBS)-CMC and (N-PBS)-HEC were calculated using molecular dynamics simulation. In addition, the interaction mechanism of composites was explained using Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). The molecular dynamics simulation results indicated that the hydrogen bonding, physical absorption, and electrostatic interaction produced between -OH, -OCO-, -COOH, and -N-CH 2 -functional groups. The (N-PBS)-HEC composite displayed more stable system than that of (N-PBS)-CMC composite. The results were explained using absorption peak of functional groups in FTIR and the binding energy distribution change of C1s, O1s, and N1s elements in XPS and smooth surface between N-PBS and HEC.

Natural based composites of hydroxyapatite/Gum Arabic designed for removal of toxic metal arsenic (III) from waste water were synthesized and evaluated. Several composites with various compositions were prepared by the wet chemical method and analyzed using various spectroscopic and analytical methods such as: Fourier transform infrared spectroscopy, total organic carbon production, XRD analysis and scanning electron microscope. The rates of weight loss and water absorption of the HAp/GA composites as a function of time were evaluated in phosphate-buffered saline solution at 37 °C and a pH of 7.4. The effects of several variables on adsorption of arsenic (III) by HAp/GA composites were evaluated. The variables include arsenic (III) concentration, contact time (t) and complex surface nature of HAp/GA composite. Three surface complexation models were used to study the mechanisms controlled the adsorption. The models were Langmuir, Freundlich and Dubinin Radushkevich. The adsorption kinetic of arsenic (III) on the composite surface was described by three modes: pseudo first order, pseudo second order and the intra particle diffusion. The results revealed that, the rate of adsorption of arsenic (III) by HAp/GA composites was controlled by two main factors: the initial concentration of arsenic (III) and the contact time. The kinetic studies also showed that, the rate of adsorption is a second order. The results indicate that, composite offered in this study could be a valuable tool for removing toxic metals for contaminated water by adsorption.Graphical abstract.
