The Adsorption Potential of Cr from Water by ZnO Nanoparticles Synthesized by Azolla pinnata
(2022 , Article)Aqueous solutions containing toxic elements (TEs) (such as hexavalent chromium (Cr (VI)) can be toxic to humans even at trace levels. Thus, removing TEs from the aqueous environment is essential for the protection of ... -
Aquaculture sediments amended with biochar improved soil health and plant growth in a degraded soil
( Elsevier , 2023 , Article)Sustainable and safe management of aquaculture sediments is of great concern. Biochar (BC) and fishpond sediments (FPS) are rich in organic carbon and nutrients and thus can be used as soil amendments; however, it is not ... -
Distribution, pollution, and human health risks of persistent and potentially toxic elements in the sediments around Hainan Island, China
( Elsevier , 2022 , Article)Human activities have changed the global concentration of potentially toxic elements (PTEs) and significantly altered the marine ecosystem. Little is known about the concentrations of these PTEs around Hainan Island in ... -
A green method for removing chromium (VI) from aqueous systems using novel silicon nanoparticles: Adsorption and interaction mechanisms
( Elsevier , 2022 , Article)In the present study, we used the horsetail plant (Equisetum arvense) as a green source to synthesize silicon nanoparticles (GS-SiNPs), considering that it could be an effective adsorbent for removing chromium (Cr (VI)) ... -
Green synthesized zinc oxide nanoparticles for removal of carbamazepine in water and soil systems
( Elsevier , 2024 , Article)During the COVID-19 pandemic, there was a significant increase in pharmaceutical releases (4 %), which created a pressing global need for solutions. In this study, we explored the use of zinc oxide nanoparticles (GS-ZnONPs) ... -
Study on application of green-synthesized ZnO and Si nanoparticles in enhancing aquaculture sediment quality
( Springer , 2025 , Article)Background: Fishpond sediments (FPS) are rich in organic carbon and nutrients, making them valuable as fertilizers and soil conditioners. Stabilizing heavy metals like chromium (Cr), copper (Cu), and zinc (Zn) is essential ... -
A systematic review on the bioremediation of metal contaminated soils using biochar and slag: current status and future outlook
( Springer , 2023 , Article Review)Heavy metals contaminated soils are posing severe threats to food safety worldwide. Heavy metals absorbed by plant roots from contaminated soils lead to severe plant development issues and a reduction in crop yield and ...
