In this work, magnetic ZnFe 2 O 4 nanotubes (ZFONTs) were synthesized, characterized and used as adsorbent for dispersive micro-solid phase extraction of Co(II), Ni(II), Mn(II) and Cd(II) before their determination by inductively coupled plasma mass spectrometry. Adsorption behaviors of target ions on ZFONTs were investigated. The results showed that the analytes were quantitatively retained on ZFONTs in the pH range of 6.0–8.0, and eluted completely with 1.0 mL of 0.4 mol L −1 HNO 3 . The separation of sorbent from aqueous phase was performe...
