Abstract The study shows an innovative method for boron waste treatment through synthesizing mesoporous silica (MCM-41) from it. At the initial stage of the process, magnesium was extracted from the waste by HCl solution and the silica source was leached by sodium hydroxide solution from the residue. Afterwards, n-hexadecyltrimethyl ammonium bromide (CTAB) was employed as the template. XRF investigated the influence of HCl/boron waste ratio, reaction time and temperature on preparing silica sour...

Abstract Carbon monoxide is a feedstock used in the petrochemical industry for production of many chemicals. These processes require separation or purification of CO. Adsorption is a cost and energy-effective method of separation that can provide high CO adsorption capacity and selectivity with correct selection of adsorbent. In this review, an overview of equilibrium and dynamic adsorption setups with equilibrium and kinetic models of adsorption are presented. Adsorption data collection using e...

Abstract Here, we present a pathway for the green synthesis of Ag/AgCl nanoparticles derived from freshwater Chara vulgaris algae. The formation of Ag/AgCl NPs is confirmed by XRD, UV–Vis spectroscopy, and SEM techniques. The volume with an aqueous extract of Chara vulgaris: AgNO3 ratio 3:1 possessed optimal synthesised Ag/AgCl NPs. A plasmon absorbance peak, at 395 nm was observed in the UV–vis spectrum. XRD patterns confirmed the highly crystalline FCC structure of Ag/AgCl NPs. SEM imaging of ...

Abstract Monolithic TiO2 and Ni2P dispersed 2D Ti3AlC2 MAX nanocomposite synthesized by sol-gel method, was investigated for stimulating photocatalytic H2 production. The performance was tested in three types of photoreactors including visible light irradiated slurry, visible and UV light irradiated fixed-bed and monolith photoreactors in batch and continuous operation. Using TiO2/Ni2P/Ti3AlC2 highest H2 production was achieved, which was 1.13, 3.25 and 3.80 times higher compared to TiO2/Ti3AlC2...

ABSTRACT This study is focused on the recovery of polyphenols from vegetable and fruit residues and further evaluation of antioxidant features of extracts. Spinach and orange have been selected as representative matrices for a more comprehensive study since they contain significant polyphenols amount that could be used in food, pharmaceutical and/or cosmetic industries. Extraction of polyphenols from spinach and orange waste was performed using three extraction techniques: ultrasound-assisted ex...

Abstract Classical Fe-based Fenton catalysts have limited applications due to many disadvantages. Herein, Cu+/g-C3N4 catalysts were successfully prepared by a one-step thermal polymerization method. The physicochemical of g-C3N4 and Cu+/g-C3N4 were characterized by XRD, SEM, FTIR, XPS and BET. The best performance of Cu+/g-C3N4(1:4) catalyst can be obtained when the doping molar ratio of CuSO4·5H2O to melamine is 1:4, which appeared as flakes with abundant mesopores and the BET specific surface ...

Abstract In the present work, a new nanocomposite, reduced graphene oxide (rGO) decorated by mercaptamine- gold nanoparticles (AuNPs-MCA-rGO) was synthesized for the first time by a facile hydrothermal method. The carbon ionic liquid electrode (CILE) was modified by AuNPs-MCA-rGO and molecular imprinted polymer (MIP) to sensitive and selective electrochemical microanalysis of bisphenol A (BPA). The modifier provides a large surface area, selective sites and exhibited a rapid electron transport r...

Abstract The substrate of RO thin film composite membranes offers support for rejection layer formation. It remarkably affects the physicochemical and structural properties of the developed rejection layer. This denotes the relevance of substrates modification in realizing optimized substrate structure in terms of porosity, thickness and tortuosity with the goal of obtaining highly selective and enhanced hydrophilic membrane. Polyamide thin film nanocomposite (TFN) membranes with its polysulfone...

Abstract Forward osmosis (FO) is a membrane separation technique used to recover water from feed solution (FS) across a semi-permeable membrane, using a concentrated draw solution (DS). The feed solution could be sea/brackish water, wastewater, or other contaminated water. The DS and membrane play important roles in its overall performance. Permeate in FO is not pure water but a diluted DS. So, FO requires an additional step to regenerate DS and to recover freshwater as a product. This additiona...

Abstract This study aims to evaluate the influence of operational factors (i.e. substrate concentration, activated sludge concentration and acclimation concentration) and the microbial communities of activated sludge on the aerobic biodegradation of phenol and p-nitrophenol (PNP). During the biodegradation process, the phenol or PNP biodegradation and activated sludge growth kinetics were determined and the interaction effects of the operational factors on the kinetics were assessed. The phenol ...
