Abstract Global water pollution is becoming increasingly serious, and compound pollutants such as heavy metals and organic dyes pose multidimensional threats to ecology and human health. Metal-organic skeleton compounds (MOFs) have been proven to be highly efficient in capturing a variety of pollutants by virtue of their large specific surface area, adjustable pore channels, and abundant active sites. However, the easy agglomeration of powders, the difficulty of recycling, and the poor long-term stability have limited their practical applications. Cellulose, as the most abundant renewable polymer in nature, has the characteristics of a three-dimensional network, mechanical flexibility,… More >

Abstract In this study Fe doped SnO₂-SnS₂ (FS) and Fe doped SnO₂-SnS₂-polypyrrole (FS-PPY) were synthesized and studied for the methylene blue (MB) egrdation under UV light. The morphological and structural characterizations were carried out by FTIR, SEM-EDX, XRD and XPS. It has been found that FS-PPy degrade methylene blue upto 98 % under optimized conditions as pH =3, dye concentration = 10 ppm, oxidant dose = 2 mM. The Langmuir-Hinshelwood kinetics model fitted well. The optimization was studied using response surface methodology. Scavengers study was carried out to find the active species. Reusability of photocatalyst was evaluated More >

Abstract Wastewater generated by the textile industry contains high levels of various pollutants. Advanced conventional methods, such as chemical and electrical treatments, are effective in addressing these contaminants. However, the significant operational and capital costs associated with these conventional systems limit their accessibility for industrial stakeholders. In contrast, more economically viable methods tend to be less efficient. This study aims to identify a suitable approach for integrating photocatalytic degradation (PCD) with a low-cost method to enhance the cost-effectiveness of wastewater treatment processes in the textile sector. The study utilized silver copper sulfide (AgCuS) nanocomposites as a… More >

Abstract With the rapid development of industry, the environmental problems caused by heavy metal arsenic and antimony are becoming increasingly serious. Therefore, it is urgent to solve the problem of arsenic and antimony pollution in the water environment. Renewable carbon-based materials, as a kind of adsorbent widely used in wastewater treatment, have been the focus of scholars’ research for many years. In this review, the preparation methods, characteristics, and applications of renewable carbon-based materials (biochar, activated carbon, carbon nanotubes, and graphene) for the removal of arsenic and antimony are described in detail. Based on adsorption kinetics,… More > Graphic Abstract

Abstract Chromium (Cr), a persistent soil pollutant, has detrimental effects on plants and living things, and its contamination in soil increased as a result of human-induced activities. Pakistan suffers from a lack of fresh water supplies; hence most people use metal-containing water and wastewater to irrigate their crops. Exposure to Cr toxicity, the plant reduces their morphological and physiological growth which ultimately decreases crop productivity. The current study was designed to investigate the foliar application of hesperidin (HSP) at varying effluent rates (25, 50, 75, and 100 mg L⁻¹) on wheat growth under tannery wastewater irrigated soil.… More >

Abstract The development of Indonesia’s New Capital City (Ibu Kota Negara (IKN)) does not only offer opportunities but also faces uncertainties. One of these concerns is wastewater management, in terms of volume, location, and treatment facilities. To evaluate how the city might be able to manage this, this study starts with a theoretical evaluation of which wastewater management principles are crucial. Then the empirical study evaluates where and how the current infrastructure of the IKN could manage the wastewater and assesses—based on spatial scenarios—if the current wastewater management plans for the IKN are adequate.

Abstract The current research work investigated the photocatalytic degradation of dye using polythiophene-based silver-doped zinc sulfide (PT/Ag-ZnS). The ternary composite was synthesized by in-situ chemical oxidation polymerization approach and thoroughly characterized. Maximum photocatalytic activity depicted > 80% for Ag-ZnS and > 94% for PT/Ag-ZnS at pH 7 and 4 respectively at 10 mM oxidant and 30 mg/100 mL catalyst dose, 10 ppm IDC under 90 min. DMSO serves as an effective radical scavenger. The novel polymeric composite exhibits efficient reusability upto five cycles. Pseudo 1^st -order kinetic model was best fitted for PT/Ag-ZnS.

Abstract 3D printing technology has demonstrated considerable potential in wastewater remediation. Zero-valent metal (ZVM) has been recognized as an efficient catalyst facilitating the organic pollutant degradation in water. However, owing to its inclination toward oxidation and aggregation, the practical utilization of ZVM remains a challenge. Herein, we have employed 3D printing techniques to fabricate hierarchically porous ZVM, such as zero-valent copper and zero-valent iron, which exhibit a high level of printing precision and commendable resistance to compression. These 3D-ZVM catalysts can effectively activate peroxymonosulfate (PMS), thereby degrading various organic pollutants, including tetracycline, ciprofloxacin, rhodamine B, and… More >

Abstract The pursuit of incorporating eco-friendly reinforcing agents in polymer composites has accentuated the exploration of various natural biomass-derived materials. The burgeoning environmental crisis spurred by the discharge of synthetic dyes into wastewater has catalyzed the search for effective and sustainable treatment technologies. Among the various sorbent materials explored, biochar, being renewable, has gained prominence due to its excellent adsorption properties and environmental sustainability. It has also emerged as a focal point for its potential to replace other conventional reinforcing agents, viz., fumed silica, aluminum oxide, treated clays, etc. This study introduces a novel class of… More > Graphic Abstract
