ULTRAEFFICIENT SEPARATION AND SENSING OF MERCURY AND METHYLMERCURY IONS IN DRINKING WATER BY USING AMINONAPHTHALIMIDE-FUNCTIONALIZED FE3O4@SIO2 CORE/SHELL MAGNETIC NANOPARTICLES

摘要

The present invention relates to a Fe ₃ O ₄ / SiO ₂ core / shell magnetic nanoparticles having an aminonaphthalimide group substituted on the surface of the shell, and to a method and application thereof. In detail, mercury and organic mercury can be detected with high sensitivity from drinking water contaminated with mercury and organic mercury, and an aminonaphthalimide group, which can separate and remove mercury and organic mercury from contaminated drinking water through chemical and physical adsorption, is formed on the surface of the shell. The present invention relates to a substituted Fe ₃ O ₄ / SiO ₂ core / shell magnetic nanoparticle and a method for manufacturing the same, and to a technology applicable to an optical sensor and a water purifier using the magnetic nanoparticle.
