A tin (Sn) nanostructure has been applied to a gas diffusion electrode for the direct electro-reduction of carbon dioxide (CO<sub>2</sub>) in zero-gap electrolytic cell.
Azo dyes in industrial textile and dye effluent (5–30%) have become irresistibly recalcitrant toxic to both treatments the environment respectively. Global concerns about persistent nature of these limitation conventional treatment currently place led this critical analysis evaluation photocatalytic approach using nano-technology. The review literature has indicated that although is effective, however, frequent electron-hole recombination during process coupled with challenges agglomeration...
Various integrated technologies have been investigated for the remediation of heavily polluted industrial dye effluent. Also, more than 70 % these dyes are known to be solely azo used in textile industry with 5–30 presence effluent as loose molecules which recalcitrant treatment. These challenges led investigation energy-efficient processes (solar) and fabrication high-performance nano-photocatalysts proficient photocatalysis while mediating process Fenton reagents. The study fabricated...
Abstract In this work, Ag–ZnO nanocomposites were prepared by a green synthesis route using aqueous leaf extract of Tetradenia riperia and investigated for antibacterial activity against Escherichia coli Staphylococcus aureus. To optimize the Ag–ZnO, effects precursor concentrations, pH, temperatures studied. The characterized XRD, ATR-FTIR, FESEM, TEM. Results show that concentration 8% Ag, temperature 80 °C, pH 7–8 optimal nanocomposites. XRD analysis showed decrease in particle size from...
Abstract The municipal solid wastes (MSW) management technologies in most cities of developing countries pose a continuous risk contaminating the environment and affecting human health adversely; often because MSW are not comprehensively analyzed before their implementation. For this purpose, life cycle assessment methodology was applied to access different scenarios Arusha City, Tanzania. Three recycling sanitary landfilling (RSL) were developed as business usual scenario (SN-1), RSL...
The present study describes the synthesis and characterization of a hydroxyapatite (HAp)-based adsorbent derived from biogenic cockle (Anadara granosa) shells for defluoridation drinking water. raw synthesized HAp were characterized by X-ray fluorescence spectroscopy (XRF), attenuated total reflection-Fourier transform infrared (ATR-FTIR), diffraction (XRD), Field emission scanning electron microscopes-energy dispersive (FESEM-EDX) Brunauer-Emmett-Teller (BET) surface area analysis. As...
Microplastic pollution (MPs) emerged as a significant environmental concern due to its persistent nature. These MPs particles endure in waters, soils, and even the atmosphere, posing potential threats entire ecosystem. Aquatic organisms are at risk of ingesting MPs, leading accumulation tissues, ultimately affecting food chain. This study aims provide an overview sources distribution, impacts. have been documented various substances such bottled water, salts, seafood, air. However, full...
Antiviral drugs such as lamivudine have been globally identified in the environment and marked emerging pollutants of concern due to their bioactive extremity. Following therapeutic uses, approximately 70% oral dose is eliminated renally parent drug. Concerns has raised for neighbouring aquatic bodies effluent produced from production plants containing high concentrations antiviral drugs. drugs, lamivudine, are extremely bioactive, prompting interest urgent removal environment. The purpose...
The textural properties and surface chemistry of activated carbon support are commonly known to have influence on the catalytic performance catalysts. Many authors assessed effect in deoxygenation triglycerides. This review focuses reconciling literature role/relevance triglycerides into diesel-like hydrocarbons. It is revealed that different (AC) exhibit distinct effects behaviors supported catalyst. degree both AC varies with nature
Abstract The quest to synthesize safe, non-hazardous Ag–ZnO nanoomposites (NCs) with improved physical and chemical properties has necessitated green synthesis approaches. In this research, Launaea cornuta leaf extract was proposed for the of NCs, wherein used as a reducing capping agent. antibacterial activity prepared investigated against Escherichia coli Staphylococcus aureus through disc diffusion method. influence temperature, pH, precursor concentration on NCs antimicrobial efficacy...
Scientific interest in antimicrobial pollutants, such as ciprofloxacin, has increased. Due to spread of antibiotic-resistant bacteria, resistance genes, and their dissemination the environment. Therefore, remediation is necessary ensure ecological sustainability. The current study aimed optimise removal ciprofloxacin from synthetic water using jamun seed (JS) (Syzygium cumini) biochar a response surface methodology (RSM). Result indicates elimination efficiency ranged between 32.46 94.95%,...
