摘要：

Sulfonated ion irradiated (H+ and He2+) PEEK films were synthesized with a range of cross-linking density and a variety of sulfonation degrees. Batch adsorption experiments were carried out at an initial pH of 6.0 +/- 0.2, initial concentrations of Pb2+ and Cs-137 ions of 10.0mgL(-1) and 5500BqL(-1), respectively. The maximum adsorption capacity was 60mgg(-1) for Pb2+, and the distribution coefficient reached 6200cm(3)g(-1) for Cs-137. The results indicated that sulfonation could be used to recycle low cross-linked PEEK and prepare efficient adsorbents to remove toxic Pb2+ and Cs-137 from polluted aqueous solutions.
