“…The laponite spectrum showed a multicomponent wide band between 3700 and 3000 cm -1 , which was assigned to the stretching and bending of surface hydroxyl groups (Si-OH and Mg-OH) and at 1630 cm -1 related to adsorbed water on laponite XLG. The stretching of Si O and Si-O-Si bonds appeared as a strong band at 957 cm-1 and the stretching of Mg-O is ascribed by a band at 640 cm -1 [33,47].…”

Pervaporation (PV) has shown great promise in water desalination technology. In this work, laponite XLG-Poly (vinyl alcohol) (PVA-Lap) mixed matrix membranes (MMMs) were fabricated to investigate the elaboration of desalination of high-salinity water by pervaporation. The influence of laponite content on the morphology, chemical structure and hydrophilicity of the membranes was investigated. In addition, salt transport properties in the membranes were observed. Moreover, the effect of different laponite content in the PVA matrix on the desalination performance was observed at temperatures from 40°C to 70 °C and feed solutions with up to 10 wt% NaCl. The prepared MMMs showed higher hydrophilicity and roughness of the surface and higher mechanical stability. The higher water flux of 58.6 kg/m 2 .h with a salt rejection over 99.9 % was achieved using 2 wt% laponite XLG MMMs desalinating 3 wt% aqueous NaCl solution at 70 °C. The salt permeability in the membrane was lower by two orders of magnitude than that of water. The water/salt selectivity increased, while the water permeability decreased, with increasing of laponite content in the membrane.

“…In this stage, adsorption occurred less efficiently due to the gradual occupancy of active site [16]. This type of adsorption pattern was observed in several studies done by others researchers on various heavy metals or adsorbents [17][18][19].…”

“…Herein, Mahdavinia and coworkers studied double physically crosslinked magnetic hydrogel beads by mixing sodium alginate and poly(vinyl alcohol) (PVA) containing magnetic laponite. They reported that the hydrogel beads were stable under different pH values without any disintegration and exhibited a maximum adsorption capacity for bovine serum albumin at pH = 4.5 .…”

A reinforced double network (DN) hydrogel as a candidate for skin scaffold was prepared. It consists of Ocarboxymethyl chitosan, polyvinyl alcohol, honey, CaCl 2 , and graphene oxide. The various concentrations of CaCl 2 , namely, 30, 45, and 60 wt% were investigated. Besides, the GO content was studied as 3, 5, and 10 wt%. The structure of the DN was characterized by Fourier-transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction, energy dispersive X-ray and Brunauer-Emmett-Teller were evaluated. The mechanical properties were studied, too. It showed that the DN with 45 wt% CaCl 2 was optimized. Also, swelling mechanism was investigated. Moreover, with the increase in GO content, the mechanical strength was increased. The cytotoxicity was evaluated and it was indicated that DN with 45% CaCl 2 and 5% GO had an acceptable level of biocompatibility. Moreover, scanning electron microscopy images showed the porous structure of the DN nanocomposite. Thus, the DN has the potential to be applied in tissue engineering as a skin scaffold. POLYM. ENG.
