Background: Studies have confirmed the ubiquitous presence of microplastics in every environmental compartment, and their number is rising year by year. Despite the fact that important efforts are being made in many countries to try to reduce microplastics contamination, it is very likely that their presence will continue to increase since plastic degradation is a long-term procedure. Current scientific data in this field is only the Read More

Background: The extensive industrialization and unrestricted development of dyeutilizing industries coupled with the shortage of proper effluent treatment methods have increased the water pollution. Disposal of dyes in a natural water system is a severe worldwide concern owing to the harmful effects on the ecosystem. Among the available wastewater treatment methods, adsorption is considered as a promising alterna Read More

Background: Plants are considered an important feedstock for cellulose, although algae can be used as a reservoir for the extraction of cellulose in its pure form. Cellulose nanofiber extracted from plant and algae gains more attention among researchers due to their size in the nano range, low cost for preparation, higher surface area available for tuning, outstanding mechanical properties and eco-friendly nature. However, the Read More

Background: There is an increasing demand for innovation in petroleum system replacements. Towards this aim, lignocellulosic biomass is suggested as a possible sustainable source for the manufacturing of fuels and chemical production. This paper aims to investigate different kinds of β-O-4 lignin model compounds for the production of value-added chemicals in the presence of ionic liquids. Especially, cheap β-O-4 ligni Read More

Background: Dye contamination of natural water system is a severe problem due to the considerable enhancement in the industrial activities. As the dyes are highly visible, nonbiodegradable, and toxic in nature, they are considered as a severe source of water pollution. Therefore, it is imperative to develop an inexpensive, simple, effective, and easy technique for their elimination from wastewater. Methods: Luffa aegyp Read More

Background: Color effluents generated from the production industry of dyes and pigments and their use in different applications, such as textile, paper, leather tanning, and food industries, are high in color and contaminants that damage the aquatic life. It is estimated that about 105 of various commercial dyes and pigments amounted to 7×105 tons are produced annually worldwide. Ultimately, about 10-15% is wasted i Read More

Background: Application of nanotechnology in wastewater treatment is the solution to cope with the conflict between people’s increasing demand for water and the world-wide water shortage. The main goal of this study is to prepare modified carbon nanostructures (CNSs) from sugarcane bagasse waste (SCB) as effective adsorbents for removing toxic Cr(VI) ions from their aqueous solutions. Methods: The preparation of C Read More

Background: Sucralose is a high intensity artificial sweetener and chemically known as 1,6-dichloro-1,6-dideoxy-β-D-fructofuranosyl-4-chloro-4-deoxy-α-D-galactopyranoside. It is used as a sweetener and flavour enhancer in foods and beverages. Due to its high stability at wider temperatures and pH, it made its applicability in various food products throughout the world. As per Joint FAO/WHO Expert Group on Foo Read More

Background: Because of their intrinsic ability to induce physiological effects in humans at low doses, pharmaceuticals and personal care products (PPCPs) are a unique group of emerging environmental pollutants. A number of studies have confirmed the occurrence of different PPCPs in the environment, which raises concerns about possible adverse effects on humans and wildlife. The removal of PPCPs from wastewaters ha Read More

Background: Due to an abrupt increase in the contamination of freshwater systems by dye-containing wastewater, there is an urgent need to find robust and greener adsorbents for the elimination of dyes from the contaminated water. As the dyes not only change the appearance of water but are also a cause of many serious problems, which can be some time mutagenic and carcinogenic. Methods: This research paper is base Read More

Background: The approach for the determination of aminoimidazo-azaarenes (AIAs) is urgently required due to their mutagenic activity and potential carcinogenicity. For this purpose, a CdSe/ZnS quantum dots (CdSe/ZnS QDs)-embedded molecularly imprinted silica gel with high selectivity and sensitivity was successfully prepared and applied to analyze such target. Methods: Herein, CdSe/ZnS QDs acted as the flu Read More

Background: This work describes a fast, simple, sensitive, and low-cost method for the identification of resveratrol in different brands and varieties of red wines. Methods: It was developed based on a comparison of the UV-VIS spectra of the samples and samples enriched with different concentrations of the trans-resveratrol standard. The spectra were analyzed by chemometric principal component analysis (PCA) and m Read More

Background: Bronze spears are weapons with unique regional characteristics of the Shu culture, Southwest China in the Bronze Age, which reflect the bronze manufacturing tradition and the utilization of mineral resources of ancestors. Previous studies mainly focused on the classification, the alloy composition, or the production of bronze spearheads of the Shu culture. The purpose of this paper was to make a comprehensive Read More

Background: Bisphenols A (BPA), bisphenol S (BPS), and bisphenol F (BPF) are manufactured chemicals found in food packaging, drink containers, lotions, toys, plastic PVC flooring, and water pipes. The aim of this work is to develop simple, rapid and reliable high-performance liquid chromatography with fluorescence detector (HPLC-FLD) method for simultaneous determination of bisphenols A (BPA), bisphenol F (BPF) Read More
