摘　　要：本文研究了7-碘-8-羟基喹啉-5-磷酸及8-羟基喹啉-5-磺酸同金属离子形成的配合物在水溶液中被阴离子交换树脂吸附后所表现出来的室温磷光特性.制作了测定以Al^(3+),Ga^(3+),In^(3+),Zr^(4+)和Hf^(4+)等金属离子的室温磷光传感器.实验结果表明:离子交换树脂增稳的室温磷光对湿气不敏感,选择性高,可用于发展一类新型的金属离子传感器.It was found that immobilization of the complexes formed by 8-hydroxy-7-Iodo-5-quinolinsulfonic acid (Ferron) and 8-hydroxy-5-quinolinesulfonic acid with some metal iones on strongly anion exchange resin can lead the phosphor to have room temperature phosphorescence in aqueous, The characteristic of the RTP has been studied. Based on the Phenomena, the RTPF optosensor for Al3+, Ga3+, In3+, Zr4+ and Hf4+ has been prepared. It was shown that the RTP stabilized by ion exchange resin is insensitive to moiosture, has excellent selectivity and is suitable to prepare a new type of metal ions optosensor.
