One of the greatest challenges facing global environmental science is protection aquatic from heavy metal contamination stemming human activities. This article intended as a response to dynamic evolution industries, transportation, increased extraction fossil fuels, ever-rising consumption patterns, and unregulated discharge wastewater resulting in increasing pollution with metals. The aim extends beyond mere identification metals environment; it encompasses comprehensive analysis their modes transportation fate, thorough evaluation impacts on various trophic levels, an in-depth exploration potential toxicity. Furthermore, this looks toward fresh era stewardship, characterized by deep-seated commitment improving removal such damaging pollutants our environment. To continue foster ecological economic sustainability, set out Sustainable Development Goals 2015, develop policy, there need for pioneering methods reclamation aimed at eradicating surface waters. Such include ecohydrological biotechnologies Nature-Based Solutions (NBS) based knowledge geochemical molecular processes. Both are presented under principle 'One Health' - health environment, people animals. Due its extensive effects ecosystems, international cooperation, crucial that problem addressed scale.

Modern Carbon–Based Materials for Adsorptive Removal of Organic and Inorganic Pollutants from Water and Wastewater

Molecules, Год журнала: 2021, Номер 26(21), С. 6628 - 6628

Опубликована: Ноя. 1, 2021

Currently, a serious threat for living organisms and human life in particular, is water contamination with persistent organic inorganic pollutants. To date, several techniques have been adopted to remove/treat organics toxic contaminants. Adsorption one of the most effective economical methods this purpose. Generally, porous materials are considered as appropriate adsorbents purification. Conventional such activated carbons limited possibility surface modification (texture functionality), their adsorption capacity difficult control. Therefore, despite significant progress achieved development systems remediation, there still need novel adsorptive tunable functional characteristics. This review addresses new trends adsorbent materials. Herein, modern carbon-based materials, graphene, oxidized carbon, carbon nanotubes, biomass-derived carbonaceous matrices—biochars well composites metal-organic frameworks (MOFs) MOF-derived highly-ordered advanced removal hazardous from drinking water, process leachate. The focused on preparation these next-generation analysis performance including possible mechanisms. Simultaneously, some weak points analyzed routes conquer them. For instance, large quantities pollutants, combination other methods, like sedimentation may be recommended. A number efficient strategies further enhancing adsorbents, integrating approaches rational functionalization, composing (of two or even three types) can cost reduction regeneration must also focus future research endeavors. targeted optimization discussed associated detailed studies process, especially, multicomponent adsorbate solution, will pave bright avenue remediation.

Potential Use of Biochar from Various Waste Biomass as Biosorbent in Co(II) Removal Processes

Water, Год журнала: 2019, Номер 11(8), С. 1565 - 1565

The removal of Co(II) ions from aqueous media was done using three types biochars obtained algae waste biomass, mustard and soy biomass. biochar samples were by pyrolysis biomass resulted biofules production, at relative low temperature (600–650 °C), this procedure can be considered a suitable alternative to reduce the volume such waste. FTIR spectra recorded for each type reveal presence several functional groups that used as binding sites retention. batch biosorption experiments performed function initial concentration contact time, constant solution pH (5.0), sorbent dose (8.0 g/L), room (25 ± 1 °C). sorption showed retention reaches equilibrium in maximum 60 min, capacity follows order: Mustard (MBC—24.21 mg/g) < (SBC—19.61 (ABC—11.90 mg/g). modeling experimental data proves occurs through electrostatic interactions, process takes place until monolayer coverage is formed on outer surface biochar. This information very useful design desorption system. results treating loaded with 0.1 mol/L HNO3 solution, over 92% are desorbed recovered, least sorption/desorption cycles. All observations sustain potential use different promising media.
