In recent years, interest in nanotechnology has increased exponentially due to enhanced progress and technological innovation. tissue engineering, the development of metallic nanoparticles been amplified, especially their antibacterial properties. Another important characteristic metal NPs is that they enable high control over features developed scaffolds (optimizing mechanical strength offering controlled release bioactive agents). Currently, main concern related method synthesis oxide environmental impact. The physical chemical uses toxic agents could generate hazards or exert carcinogenicity/environmental toxicity. Therefore, a greener, cleaner, more reliable approach needed. Green synthetic come as solution counter aforementioned limitations. Nowadays, green preferred because it leads prevention/minimization waste, reduction derivatives/pollution, use non-toxic (safer) solvents. This not only biomass sources reducing for salts. biomolecules also cover synthesized act situ capping agents. Further, involvement formation process reduces toxicity, prevents nanoparticle agglomeration, improves antimicrobial activity nanomaterial, leading possible synergistic effect. study aims provide comprehensive review nanoparticles, from routes, selected solvents, parameters latest application biomedical field.

A state-of-the-art of phytoremediation approach for sustainable management of heavy metals recovery

Environmental Technology & Innovation, Journal Year: 2023, Volume and Issue: 30, P. 103043 - 103043

Published: Feb. 2, 2023

Phytoremediation is deemed as an efficient and environmentally friendly alternative which utilizes different types of hyperaccumulator plants known macrophytes for the removal heavy metal pollutants from water through mechanisms including phytoextraction, rhizofiltration, phytovolatilization phytostabilization. The phytoremediation efficiency affected by several key factors such plant species (floating, emergent submerged), surrounding climate (temperature about 27 °C with sufficient sunlight water) environmental conditions (appropriate amount sodium chloride, nutrients chelating agents at pH 5 to 6). main problem potential secondary pollution due re-released absorbed contaminants requires utmost attention. post-treatment disposal handling methods post-phytoremediation are reviewed extensively. Heat treatment method able produce valuable biochemicals high temperatures range 160 1600 °C. Extraction can extract up 99 % metals, while composting relatively low energy usage. Synthesis nanomaterials phytoremediated reduce usage hazardous chemicals but hard be upscaled. Meanwhile, phytomining economically feasible (saving $8,710 per hectare crops) restricted certain treatment. major hurdle remains in capability these achieve great balance between economic viability impacts. Therefore, ultimate goal this paper provide technical assessment perspective views optimizing performance well addressing underlaying issues corresponded available order amplify commercial value process a whole.
