| 摘 要： | 研究了将碳纳米管（MWNTs）作为一种新型分析增效试剂与非离子表面活性剂-曲拉通X-100（TritonX-100）的协同增敏作用机理，并应用于Cu^2＋与二溴羟基苯基荧光酮（DBH—PF）的络合显色体系中。结果表明，在MWNTs与TritonX-100复配的影响下，在pH=6．0～7．0磷酸盐缓冲溶液中DBH—PF与Cu^2＋形成红色络合物，其最大吸收红移至570nm，吸收值提高了222．3％。Cu^2＋含量在1～100．04μg／mL范围内符合比耳定律，回归方程A=0．141C＋0.028（C，0.04μg／mL），表观摩尔吸光系数￡=2．38×10^5L／（mol·cm），R=0．9994。在最佳实验条件下，对中草药肉桂和黄连中的铜含量进行了测定，得到了满意的结果。

| Abstract: | Here,the carbon nanotubes(MWNTs) were regarded as a novel kind of enhancing agent.A novel chromogenic system was developed by the synergic effect of MWNTs and non-ionic surfactants TritonX-100,and the mechanism was discussed in this work.A red complex of Dibromohydroxy Phenylfluorone(DBH-PF) with Cu2+ was formed in the Phosphate buffer solution in a pH range of 6.0-7.0.Comparative experiments showed that,due to the synergic effect of MWNTs and TritonX-100 the absorption of the red complexes increased by 222... |
