Magnetic nanoparticles were synthesized bya novel eco-friendly method using glutathione as a reductant and stabilizer. A careful study of the life cycle in the synthesis process was performed to assess the environmental impact caused by the production of this material. From the results it is possible to conclude that the environmental impact is much less significant than that of conventional routes, specifically the co-precipitation method with which it was compared. Nanoparticles with a saturation magnetization of 85.4 emu/g were obtained, which is similar to the maximum value obtained through the co-precipitation method. One of the main advantages of this method is the formation of magnetic nanoparticles with a coating of free and reactive –SH groups, which offers interesting possibilities for its use in environmental remediation tasks, specifically in adsorbing heavy metals such as mercury. The potential of absorbing chromium and mercury at different pH, temperature and dose values of the pollutant was evaluated, as well as establishing the kinetics and adsorption isotherms.
