In order to improve the utilization efficiency of surfactants, a novel addition mode injects surfactant vapor into the bubbles has been proposed. The effect of the cationic surfactant dodecylamine (DDA) and the frothers methyl isobutyl carbinol (MIBC) and 2-octanol on the collision between bubbles and hydrophilic/hydrophobic quartz was evaluated under three surfactant addition modes namely as: 1) vapor

Visible-Light-Driven (VLD) photocatalysis for the dye waste water treatment is impeded by the immediate recombination effect and weak redox potential of the charge carriers. Here, we report the synthesis of silver and antimony tungstate-based novel hybrid composite (Ag2WO4/Sb2WO6) with significant charge carrier partition and strong redox potential for superior photocatalysis in an aqueous medium.

The conversion of waste into reusable materials has been a focus of many researchers in recent years. Polystyrene waste converted into a cation exchange resin and used as absorbent of cadmium, copper and zinc had been concerned. In this study, the feasibility of sulfonating polystyrene waste was investigated by using sulfuric acid to form sulfonated functional groups on the polystyrene matrix and further

Carbofuran is a pesticide currently prohibited in many countries. It can cause serious damages in the nervous system and has been associated with cancer. However, CBF residues are still found in food samples around the world. Here, we develop an electrochemical non-enzymatic sensor for rapid and low-cost detection of CBF. Commercial indium tin oxide (ITO) electrodes were modified with a two-step Layer-by-Layer

Emerging desalination technologies are either a group of desalination techniques that have not undergone commercialization due to the need for technological advancements. The main drivers for developing such technologies are to reduce energy consumption, and hence cost, broaden feed water options, to reduce chemical additives, and, most importantly, to reduce the environmental impacts relative to conventional

Algae are fast-growing, microscopic, and eukaryotic organisms that can perform photosynthesis, and simultaneously fix atmospheric CO2. Algal cells contain high quantity of biofuel precursors such as starch and lipid granules. In the past decades, microalgal biomass has emerged as a potential feedstock for bioenergy generation. In the current scenario, it is being extensively explored to produce liquid

Water is the need of every individual and plays a vital role in the world’s economy. Almost 70% of freshwater is used by humans for agriculture. Agriculture and industries introduce many pollutants and contaminants into water bodies. This not only affects the quality of water but also pose serious threats to the number of aquatic species. Several techniques are known to remove the contaminants from

The picloram (4-amino-3,5,6-trichloro-2-pyridinecarboxylic acid) herbicide is widely applied to control the growth of woody plants and it has been frequently detected in aqueous environments due to its poor adsorption by soils and high leaching potential. Consequently, the removal of picloram from contaminated environmental waters is of major concern due to its adverse impacts on aquatic organisms

Covalent organic frameworks (COFs) are new generation of porous materials constructed from light elements (such as carbon, oxygen and nitrogen) linked via covalent bonds. Herein, one-pot synthesis of the composite of a COF and two-dimensional (2D) nanomaterials (graphene oxide (GO), graphitic carbon nitride (g-C3N4), and boron nitride (BN)) was reported. Melamine is poly-condensed with terephthaldehyde

Photocatalytically active building materials can contribute to better air quality by mineralizing the hazardous nitrogen oxides to nitrate. Evaluation of these materials is very important for optimization and implementation at target sites. However, the currently widely used ISO 22917-1:2016 test is unsuitable to estimate the effect on real scenarios since it employs too high concentrations and only

The electrocoagulation (EC) of Congo red dye-containing wastewater was investigated, focusing on the optimization of operational parameters and process mechanism. The EC was conducted using iron electrodes and utilizing Congo Red (CR) dye as a model pollutant. Response surface methodology (RSM) was used to investigate the effect of operational parameters (initial dye concentration, pH and inter-electrode

Herein, we report the development and characterization of a green sorbent material. For the said purpose, the chitosan’s capacity of cation sorption was enhanced by incorporating thiocarabamate group, which ultimately increases active sites for attracting the cationic species. The process was carried out by utilizing acrylomorpholine, carbon disulfide and chitosan in a single stage process. The product
