The synthetic dyes used in the textile industry pollute a large amount of water. Textile do not bind tightly to fabric and are discharged as effluent into aquatic environment. As result, continuous discharge wastewater from number industries without prior treatment has significant negative consequences on environment human health. contaminate habitats have potential be toxic organisms, which may enter food chain. This review will discuss effects water bodies, flora, degrade esthetic quality bodies by increasing biochemical chemical oxygen demand, impairing photosynthesis, inhibiting plant growth, entering chain, providing recalcitrance bioaccumulation, potentially promoting toxicity, mutagenicity, carcinogenicity. Therefore, dye-containing should effectively treated using eco-friendly technologies avoid environment, health, natural resources. compares most recent commonly remove dye wastewater, with focus advantages drawbacks these various approaches. is expected spark great interest among research community who wish combat widespread risk organic pollutants generated industries.

Bio-waste valorisation: Agricultural wastes as biosorbents for removal of (in)organic pollutants in wastewater treatment

Chemical Engineering Journal Advances, Journal Year: 2021, Volume and Issue: 9, P. 100239 - 100239

Published: Dec. 31, 2021

The conventional waste management practices dispose or incinerate agricultural and forestry waste, contributing to the environmental pollution while misusing biomass, a valuable resource with great potential of reuse. In fact, cultivation crops harvesting generate an abundant amount (e.g., stones, shells, straw) that can be used for wastewater treatment. Waste biomass may as: (i) adsorbent in its original, raw form, following ambient drying grinding; (ii) modified bio-based sorbents; (iii) source material synthesis activated carbon adsorbents through carbonization. Despite numerous publications this field examining removal wide range target pollutants (metals, metalloids, dyes, pesticides, as well emerging contaminants) by several materials, more realistic studies are still required evaluate remove residual compounds complex matrices, testing natural i.e., samples without spiking compounds. This perspective paper highlights how integrated-engineering approach help solving environmental-pollution issues related water, solid air pollution. Chiefly, application locally produced bio-waste treatment tackles water contamination, decreases overall reduces gas emissions caused transportation, and/or disposal.

Adsorption kinetics and isotherm models of heavy metals by various adsorbents: An overview

Critical Reviews in Environmental Science and Technology, Journal Year: 2023, Volume and Issue: 53(21), P. 1837 - 1865

Published: June 15, 2023

Heavy metal pollution has become one of the most severe environmental issues. Adsorption is an effective method for removing heavy metals from aquatic environments. The adsorption isotherm and kinetics models can provide information on process, maximal capacity, mass transfer steps, which are essential to evaluate performance adsorbent design system. In this review, isotherms by various adsorbents were summarized discussed in depth. First, sources technology remove reviewed. capacity Cu, Cd, Zn, Ni, Cr, As, Fe, Hg, Co, Sr, Cs biosorbents (e.g. algae, agriculture waste biochar/activated carbon, bacteria) abiotic metal–organic frameworks (MOFs), microtubes, polymers, clays, minerals, coal) systematically summarized.

Methods to prepare biosorbents and magnetic sorbents for water treatment: a review

Environmental Chemistry Letters, Journal Year: 2023, Volume and Issue: 21(4), P. 2337 - 2398

Published: May 4, 2023

Access to drinkable water is becoming more and challenging due worldwide pollution the cost of treatments. Water wastewater treatment by adsorption on solid materials usually cheap effective in removing contaminants, yet classical adsorbents are not sustainable because they derived from fossil fuels, can induce secondary pollution. Therefore, biological sorbents made modern biomass increasingly studied as promising alternatives. Indeed, such biosorbents utilize waste that would otherwise pollute systems, promote circular economy. Here we review biosorbents, magnetic sorbents, other cost-effective with emphasis preparation methods, types, mechanisms, regeneration spent adsorbents. Biosorbents prepared a wide range materials, including wood, bacteria, algae, herbaceous agricultural waste, animal waste. Commonly removed contaminants comprise dyes, heavy metals, radionuclides, pharmaceuticals, personal care products. Preparation methods include coprecipitation, thermal decomposition, microwave irradiation, chemical reduction, micro-emulsion, arc discharge. Adsorbents be classified into activated carbon, biochar, lignocellulosic clays, zeolites, peat, humic soils. We detail isotherms kinetics. Regeneration supercritical fluid desorption. also discuss exhausted adsorbent management disposal. found agro-waste remove up 68–100% while wooden, herbaceous, bacterial, marine-based 55–99% metals. Animal waste-based 1–99% The average removal efficiency modified around 90–95%, but some treatments, cross-linked beads, may negatively affect their efficiency.
