| 摘 要： | 合成了新型荧光探针单(6-对氨基苯甲酸-6-脱氧)-β-环糊精(ACD)。探讨了与Cr2O27-的识别反应。在pH4·90的NaAc-HAc缓冲溶液中,Cr2O72-能使ACD的荧光猝灭,据此建立了测定Cr(Ⅵ)的新方法,在最优化实验条件下,线性范围为5·20~1040μg·L-1,检出限1·26μg·L-1。22种常见离子干扰实验结果表明该试剂对Cr2O72-有较高的选择性识别效果。此法用于电镀液、电镀废液中痕量Cr(Ⅵ)的测定,结果令人满意。

| Abstract: | A novel fluorescence probe, mono6-o-(4-aminobenzoic acid)]-beta-cyclodextrin(ACD), was synthesized, and a new sensitive fluorescence identification reaction was studied based on the reaction of Cr2O7(2-) with compound ACD in NaAc-HAc buffer medium at pH 4.90. Under optimal conditions the determination limit was 1.26 microg x L(-1). The linear range was 5.20-1040 microg x L(-1). This method has been applied to the determination of trace amounts of chromium (VI) in electroplating liquor, electroplating waste water with satisfactory results. |
