S-quinolin-2-yl-methyldithiocarbazate-based magnetic adsorbent for magnetic solid-phase extraction of heavy metals from water samples

New S-quinolin-2-yl-methyl-dithiocarbazate-based magnetic adsorbent (MNP-SQ2MDTC) for 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 cross-linker and the...
