Pharmaceuticals of Emerging Concern in Aquatic Systems: Chemistry, Occurrence, Effects, and Removal Methods

Chemical Reviews, Journal Year: 2019, Volume and Issue: 119(6), P. 3510 - 3673

Published: March 4, 2019

In the last few decades, pharmaceuticals, credited with saving millions of lives, have emerged as a new class environmental contaminant. These compounds can both chronic and acute harmful effects on natural flora fauna. The presence pharmaceutical contaminants in ground waters, surface waters (lakes, rivers, streams), sea water, wastewater treatment plants (influents effluents), soils, sludges has been well doccumented. A range methods including oxidation, photolysis, UV-degradation, nanofiltration, reverse osmosis, adsorption used for their remediation from aqueous systems. Many commercially limited by toxic sludge generation, incomplete removal, high capital operating costs, need skilled maintenance personnel. Adsorption technologies are low-cost alternative, easily developing countries where there is dearth advanced technologies, personnel, available capital, appears to be most broadly feasible removal method. integrated (WWTPs). Herein, we reviewed literature (1990–2018) illustrating rising contamination concerns efforts emphasizing adsorption.

Fixed-bed column adsorption study: a comprehensive review

Applied Water Science, Journal Year: 2019, Volume and Issue: 9(3)

Published: March 16, 2019

Present paper involved the review of fixed-bed column studies for removal various contaminants from synthetic wastewater. Basic concept adsorption, its types (i.e., chemisorption and physisorption) mechanism, adsorbents adsorbates were included. Comparison batch adsorption study is mentioned. Complete breakthrough curve designing adsorptive interpreted. This explicates detailed explanation process parameters isotherm models study. Fixed-bed using adsorbates, i.e., metal, ion, dye other hazardous materials, are reviewed, in which chromium metal most exploitable. Conclusion some challenges utilization real world also exposed.

Biochar for agronomy, animal farming, anaerobic digestion, composting, water treatment, soil remediation, construction, energy storage, and carbon sequestration: a review

Environmental Chemistry Letters, Journal Year: 2022, Volume and Issue: 20(4), P. 2385 - 2485

Published: May 7, 2022

Abstract In the context of climate change and circular economy, biochar has recently found many applications in various sectors as a versatile recycled material. Here, we review application biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, energy storage. The ultimate storage reservoirs are soils, civil infrastructure, landfills. Biochar-based fertilisers, which combine traditional fertilisers with nutrient carrier, promising agronomy. use feed additive animals shows benefits terms growth, gut microbiota, reduced enteric methane production, egg yield, endo-toxicant mitigation. Biochar enhances digestion operations, primarily biogas generation upgrading, performance sustainability, mitigation inhibitory impurities. composts, controls release greenhouse gases microbial activity. Co-composted improves soil properties crop productivity. Pristine engineered can also be employed water remediation to remove pollutants. added cement or asphalt, thus conferring structural functional advantages. Incorporating biocomposites insulation, electromagnetic radiation protection moisture control. Finally, synthesising materials requires additional functionalisation.

Review on recent progress in chitosan/chitin-carbonaceous material composites for the adsorption of water pollutants

Carbohydrate Polymers, Journal Year: 2020, Volume and Issue: 247, P. 116690 - 116690

Published: June 28, 2020

Chitosan and chitin are categorized as low cost, renewable eco-friendly biopolymers. However, they have mechanical properties unfavorable pore in terms of surface area total volume that limit their adsorption application. Many studies shown such weaknesses can be avoided by preparation composites with carbonaceous materials from these This article provides a systematic review on the chitosan/chitin-carbonaceous material composites. Commonly used activated carbon, biochar, carbon nanotubes, graphene oxide to prepare discussed. The application for various water pollutants, regeneration reusability adsorbents also included. Finally, challenges future prospects applied pollutants summarized.
