The presence of algae in aqueous environments causes many problems, such as Oxygen depletion, eutrophication, the production of slimy and jelly-like substances, the formation of trihalomethanes (THMs), and corrosion. For instance, in waste stabilization ponds - as one of the cheapest methods of wastewater treatment- wastewater is treated by the help of coexistence of algae and microorganisms, the presence of algae in the effluent can be one of the main concerns of this treatment method. So far, various physical and chemical methods have been used for algae removal, which has many disadvantages, including the entry of chemicals into the water, low efficiency, high energy consumption and long-term problems in the wastewater receiving environment. Magnetic nanoparticles have gained extremely high attention, due to their reusability, the simplicity in testing methods and separation aqueous phase, short reaction time, high efficiency, low cost and not using of toxic materials. In this study, the core@shell magnetic nanoparticles functionalized with 2,4,6- diethylentriamino-1,3,5-triazine were synthesized for the first time and then have been used in harvesting green-blue microalgae. These magnetic nanoparticles could harvest more than 99% of the green-blue microalgae within a minute. In this research, the synthesized nanoparticles were characterized by different techniques used such as FT-IR, TGA, XRD, VSM, EDX, FE-SEM, CHNS, UV-Vis, Zeta potential.
