In recent years, different approaches for achieve the removal of Contaminant Emerging Concerns (CECs) from aqueous matrices were developed. Within this framework, synthesis new hybrid materials capable to combine processes, such as photocatalysis, adsorption and enzyme catalysis, is an important issue. Therefore, enhance performances efficiency, reduce costs environmental impact these reusable synthesized tested towards both natural spiked water containing organic inorganic pollutants. The...
The use of hydrogen peroxide (produced in situ or ex situ) as the main agent oxidative processes environmental pollutant removal is widely studied. degradation water pollutants, such dyes, pharmaceuticals, cosmetics, petroleum derivatives, and even pathogens, has been successfully obtained by different techniques. This review gives an overview more recent methods developed to apply mediated H2O2 other reactive oxygen species (ROS) catalysis, with particular attention strategies (Fenton-like...
Soluble bio-based substances (SBO) have been isolated from urban waste. Their structural similarity with natural organic matter suggested exploring their activity in the photodegradation of substrates. In this work, they are shown to promote monochlorophenols. Experiments performed 1.0 × 10–4 M substrate solutions irradiated by simulated solar light presence SBO showed progressive degradation all probe The experimental data were fitted a pseudo-first-order kinetics, and rate constant was...
We have explored the impact of incorporation nanoporous carbons as additives to tungsten oxide on photocatalytic degradation two recalcitrant pollutants: rhodamine B and phenol, under simulated solar light. For this purpose, WO3/carbon mixtures were prepared using three carbon materials with different properties (in terms porosity, structural order surface chemistry). Despite low content used (2 wt. %), a significant increase in performance semiconductor was observed for all catalysts....
Abstract Soybean hulls (SBHs) are one of the main by-products soybean crushing, usually destined for animal feeding or to become a putrescible waste. In this work, we upgraded SBHs materials with antimicrobial properties. After extraction peroxidase from SBHs, an enzyme applicable in different technological sectors and naturally present hulls, exhausted biomass was subjected acid–base treatment isolate cellulose. The obtained material was, turn, functionalized 3-aminopropyl triethoxysilane...
The growing utilization of renewable and residual biomasses for environmental preservation remediation are important goals to be pursued minimize the impact human activities. In this paper, sodium alginate (derived from brown algae) was crosslinked using chitosan (mainly derived exoskeleton crustaceans) in presence biowaste-derived substances isolated green compost (BBS-GC), produce hydrogels dried films. obtained materials were tested as adsorbents wastewater remediation. To purpose, gels...
Abstract Microfluidic reaction devices are a very promising technology for chemical and biochemical processes. In microreactors, the micro dimensions, coupled with high surface area/volume ratio, permit rapid heat exchange mass transfer, resulting in higher yields rates than conventional reactors. Moreover, lower energy consumption easier separation of products these systems to have environmental impact compared macroscale, Due benefits, use microreactors is increasing biocatalysis field,...
In recent years, there has been increasing attention focused on various products belonging to the imidazopyridine family; this class of heterocyclic compounds shows unique chemical structure, versatile optical properties, and diverse biological attributes. The broad family imidazopyridines encompasses different heterocycles, each with its own specific properties distinct characteristics, making all them promising for application fields. general, useful category aromatic heterocycles holds...
The visible light induced cationic polymerization of epoxides can be achieved by means multiwalled carbon nanotubes (MWCNTs), which act as photoinitiators via a radical-induced photopolymerization process. When MWCNTs are irradiated with longer wavelengths (above 400 nm), they generate radicals, hydrogen abstraction from the epoxy monomer; these radicals oxidized in presence iodonium salt to carbocation that is sufficiently reactive start ring-opening an monomer. These mechanisms have been...
The current SARS-CoV-2 pandemic causes serious public health, social, and economic issues all over the globe. Surface transmission has been claimed as a possible infection route, especially in heavy contaminated environmental surfaces, including hospitals crowded places. Herein, we studied deactivation of on photoactive AgNPs@TiO2 coated industrial ceramic tiles under dark, UVA, LED light irradiations. inactivation is effective any light/dark conditions. presence AgNPs an important key to...
In this work, we synthesized and characterized carbon nitride (CN) nanoparticles obtained by the thermal treatment (550 °C) of urea, melamine, dicyandiamine, dicyandiamine-barbituric acid in an open reactor evaluated effect different precursors on photocatalytic performance. CNs from were 3D melon-type structures. On other hand, CN urea was a 2D microporous, amorphous structure whose melon or graphitic arrangement could not be determined. The presence structural defective states (mainly C...
The agri-food supply chain and other industries that convert agricultural raw materials into various consumer goods generate large quantities of by-products, most which end up in landfills. This waste, rich cellulose, provides a significant opportunity for the conversion residues valuable products. In this paper, soybean hulls hemp waste were subjected to chemical treatments with alkaline (NaOH 2% w/v) acidic solutions (HCl 1 M) remove non-cellulosic components isolate cellulose. biomass was...
Abstract Urban waste‐derived bioorganic substances (UW‐BOS) have shown promise as chemical auxiliaries for a number of technological applications in the industry and environmental remediation.
