The adsorption of different amounts of Pb 2+ was determined via soaking specimens (7 mg) of CelloZIFPaper into Pb 2+ solutions with the volumes of 5, 10, 20, 50, and 100 mL (1000 ppm), respectively. The materials were incubated for 12 h. The materials were digested into nitric acid (68%). The concentration of Pb 2+ metal ions was measured with FAAS.
