The CelloZIFPaper_In Situ was investigated for the adsorption of Co 2+ , Cu 2+ , and Pb 2+ from aqueous solutions. A 100 mg specimen of CelloZIFPaper_in situ (1:4 wt. ZIF: TOCNF) was added to the metal solutions (20 mL, 1000 ppm) and incubated for 12 h. The desorption was performed via stirring with acetonitrile (100 mL) for 12 h. The adsorption was recorded as percentage referring to the original adsorbed value of each metal ion. The recyclability of CelloZIFPaper was assessed following the same procedure for three cycles.
