Table 4 shows the selectivity of the anion adsorption for the 0.10 Fe-P1 zeolite. The Fe-P1 zeolite powder. (0.05 g) added to 2 ppm solutions (100 mL) was slowly shaken (Stroke: 4 cm, 1 Hz) for 24 h at room temperature. The Fe-P1 zeolite showed a high selectivity for the anions of phosphoric acid and arsenic acid.
