Green synthesis of magnetic nanoparticles for removal of mercury from contaminated water
The contamination of water for human consumption by heavy metals, is part of one of the problems that can be faced from the advantages offered by nanoparticle engineering. Within a context of sustainability and responsible use of nanomaterials, it is possible to develop efficient and safe remediation strategies: i) synthetic routes with the use of precursors, reducers and stabilizers of natural origin. This open the way to the green chemistry applied to nanotechnology. ii) Ensure conditions to prevent the mobility of nanomaterials to the environment. iii) Increase reuse and responsible management of waste from remediation tasks.
A green synthesis method for the production of functionalized magnetic nanoparticles, with a high removal capacity of mercury and possibilities of reuse and controlled use has been developed. The work includes a detailed study of the life cycle of the synthetic method and impact evaluation in environment and living beings.
