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.

Dye and nitro-compound pollution has become a significant issue worldwide. The adsorption degradation of dyes nitro-compounds have recently important areas study. Different methods, such as precipitation, flocculation, ultra-filtration, ion exchange, coagulation, electro-catalytic been adopted for the these organic pollutants. Apart from adsorption, photocatalytic degradation, chemical are considered most economical efficient to control water nitro-compounds. In this review, different kinds nitro-compounds, their adverse effects on aquatic organisms human beings, were summarized in depth. This review article covers comprehensive analysis over materials (porous polymer, carbon-based materials, clay-based layer double hydroxides, metal-organic frameworks, biosorbents). mechanism kinetics dye central parts structures all mentioned above discussed, along with main functional groups responsible adsorption. Removal also aim article, well used degradation. mechanisms explained comprehensively. factors highlighted. Advantages disadvantages, economic cost, discussed briefly. will be beneficial reader it aspects Future shortcomings part article.

Abstract In the present study, a green, sustainable, simple and low-cost method was adopted for synthesis of ZnO NPs, first time, using aqueous extract sea lavender, Limonium pruinosum (L.) Chaz., as reducing, capping, stabilizing agent. The obtained NPs were characterized ultraviolet–visible spectroscopy (UV–VIS), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), transmission (TEM), diffraction (XRD) thermogravimetric (TGA). UV–Vis spectra green synthesized showed strong absorption peak at about 370 nm. Both XRD confirmed hexagonal/cubic crystalline structure with an average size ~ 41 It is worth noting that cytotoxic effect on investigated cancer cells dose-dependent. IC 50 skin 409.7 µg/ml NPs. Also, phyto-synthesized nanoparticles exhibited potent antibacterial antifungal activity particularly against Gram negative bacteria Escherichia coli (ATCC 8739) pathogenic fungus Candida albicans 10221). Furthermore, they considerable antioxidant potential. Thus, making them promising biocompatible candidate pharmacological therapeutic applications.

The global challenges of clean water access and security are a growing concern, along with wastewater being major source pollution. Innovative approaches to remediate contaminants needed. However, sustainable development requires innovative from their source. In the last decade, extensive research has been conducted worldwide improve conventional technologies for treatment. Recent strategies include adsorption, advanced oxidation, biodegradation, membrane filtration. no technology can effectively remove contaminants, hybrid systems more promising. This review provides comprehensive overview characteristics organic pollutants degradation using various physical, chemical, biological strategies. Indeed, treatment such as nanotechnology artificial intelligence be considered planning designing modern plants. studies have indicated that compelling than single enhancing process efficiency. discussions anticipated lay foundations future improvements in could emerge promising minimize toxicity allow safe reuse water.
