Evaluating the development of sustainable nanotechnology: Synthesis by bioreduction and applications in the decontamination of industrial waters

Abstract

Water contamination due to industrial activities ha s become a latent concern due to the environmental risk and the health of people, for this reason there are more proposals for environmental remediation. One of them and the most innovative is the application of nanotechnology which can be developed by various methods. This research seeks to collect and discuss information related to the sustainable method (green synthesis) for the production of iron nanoparticles, its effectiveness to decontaminate industrial waters and what are the variables that enhance its effectiveness, this from the analysis of scientific articles between the years 2015-2020; this analysis was guided by the PRISMA methodology. The identification of literature was carried out through a search in quality databases, considering those articles with less than five years of antiquity in English and Spanish. The results show the evolution of better methodologies for the management of green synthesis processes, in addition to the potential applications of iron nanoparticles in the decontamination of aqueous media.
