Kurzfassung:
We report the extremely high and selective uptake of selenium oxyanions by a novel anion exchanger, Ni 1-x Zn 2x (OH) 2 (OCOCH 3 ) 2x n H 2 O (0.15 〈 x 〈 0.25). The tested Ni–Zn basic salt ( x =0.24) exhibited very high selectivity for Se(IV) [ K d = 9.0 × 10 4 cm 3 /g with an initial Se(IV) concentration of 1 × 10 -4 M] in the presence of 0.1 M C1 − solution. The uptake of Se(IV) on the Ni–Zn basic salt was irreversible when treated with solutions containing 1 N C1 − 1N NO 3 − or 1 N PO 4 3− This novel exchanger also showed high K d (2.6 × 10 3 cm 3 /g) for Se(VI), and therefore it is expected to be useful for decontamination and removal of selenium oxyanions from contaminated water.
