Development Of S-Quinolin-2-Yl-Methyldithiocarbazate Functionalized Magnetic Nanoparticles As Magnetic Solid Phase Adsorbent For The Determination Of Heavy Metals In Water Samples

S-quinolin-2-yl-methyl-dithiocarbazate functionalized magnetic nanoparticle(MNP-SQ2MDTC) as adsorbent in magnetic solid phase extraction (MSPE) was developed for the determination of Cd2+ and Cu2+ in water samples. The surface of MNP was first coated with 3-(aminopropyl)triethoxysilane (APTES) as cr...
