Role of Nanomaterials in the Treatment of Wastewater: A Review

Water, Journal Year: 2020, Volume and Issue: 12(2), P. 495 - 495

Published: Feb. 12, 2020

Water is an essential part of life and its availability important for all living creatures. On the other side, world suffering from a major problem drinking water. There are several gases, microorganisms toxins (chemicals heavy metals) added into water during rain, flowing water, etc. which responsible pollution. This review article describes various applications nanomaterial in removing different types impurities polluted kinds nanomaterials, carried huge potential to treat (containing metal toxin substance, organic inorganic impurities) very effectively due their unique properties like greater surface area, able work at low concentration, The nanostructured catalytic membranes, nanosorbents nanophotocatalyst based approaches remove pollutants wastewater eco-friendly efficient, but they require more energy, investment order purify wastewater. many challenges issues treatment. Some precautions also required keep away ecological health issues. New modern equipment treatment should be flexible, cost efficient commercialization purpose.

Graphene based adsorbents for remediation of noxious pollutants from wastewater

Environment International, Journal Year: 2019, Volume and Issue: 127, P. 160 - 180

Published: March 26, 2019

The contamination of water resources with noxious pollutants is a serious issue. Many aquatic systems are contaminated different toxic inorganic and organic species; coming to wastewater from various anthropogenic sources such as industries, agriculture, mining, domestic households. Keeping in view this, treatment appears the main environmental challenge. Adsorption one most efficient techniques for removing all types i.e. inorganics organics. Nowadays, graphene its composite materials gaining importance nano adsorbents. Graphene; two-dimensional nanomaterial having single-atom graphite layer; has attracted great interest many application areas (including treatment) due unique physico-chemical properties. present paper focused on remediation wastes using based adsorbents, it contains details – i.e., their synthesis field (removal hazardous contaminants chemical nature - heavy rare-earth metal ions, compounds effluents. efficiency adsorption desorption these substances considered. Certainly, this article will be useful environmentalist design future experiments treatment.

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.

Interaction of Microplastics with Antibiotics in Aquatic Environment: Distribution, Adsorption, and Toxicity

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(23), P. 15579 - 15595

Published: Nov. 8, 2021

As two major types of pollutants emerging concerns, microplastics (MPs) and antibiotics (ATs) coexist in aquatic environments, their interactions are a source increasing concern. Therefore, this work examines the interaction mechanisms MPs ATs, effect on ATs bioavailability antibiotic resistance genes (ARGs) abundance environments. First, for adsorption summarized, mainly including hydrophobic, hydrogen-bonding, electrostatic interactions. But other possible mechanisms, such as halogen bonding, CH/π interaction, cation−π negative charge-assisted hydrogen bonds, newly proposed to explain observed adsorption. Additionally, environmental factors (such pH, ionic strength, dissolved organic matters, minerals, aging conditions) affecting by specifically discussed. Moreover, could change bioaccumulation toxicity organisms, related joint reviewed analyzed. Furthermore, can enrich ARGs from surrounding environment, is evaluated. Finally, research challenges perspectives MPs–ATs implications presented. This review will facilitate better understanding fate risk both ATs.
