摘要: Abstract In the present paper, core–shell structured Fe 3 O 4 nanoparticles functionalized with rhodamine derived probe were prepared for detection, adsorption and removal of Hg(II). The core was composed superparamagnetic nanoparticles, while shell consisted silica molecular sieve MCM-41 by probe. nanocomposite characterized electron microscopy images, XRD patterns, thermogravimetric analysis N 2 adsorption/desorption isotherms, which confirmed its structure. Its sensing performance towards Hg(II) then discussed in detail. Experimental result suggested that emission increased increasing concentration, showing “Off-On” effect. High sensitivity good selectivity observed from nanocomposite. Owing to highly ordered tunnels large surface-area-to-volume ratio MCM-41, showed fast response What's more, it recyclable practical application.
