铜和铋分別检测的方法已有一些报道。A.Mizuikc等曾用玻碳电极阳极溶出法同时测定锆棉中的铜和铋,但操作复杂,不易掌握。碳纤维吸附某些痕量金属离子能改变其性能,因此,定量测定碳纤维吸附层中痕量铋等元素具有重要的意义。本文用玻碳汞膜电极差示脉冲阳极溶出伏安法,进行了碳纤维中痕量铜和铋的同时测定,并对测定条件进行了研究。本法简便易行,灵敏度高。电解30分
Methods for the detection of copper and bismuth have been reported. A.Mizuikc and other glassy carbon electrode anodic dissolution method for the simultaneous determination of zirconium in copper and bismuth, but the operation is complex, not easy to grasp. Carbon fiber adsorption of certain trace metal ions can change its performance, therefore, quantitative determination of carbon fiber adsorption layer of trace elements such as bismuth is of great significance. In this paper, glassy carbon mercury electrode differential pulse anodic stripping voltammetry, carbon fiber in the determination of trace amounts of copper and bismuth, and the determination of the conditions were studied. This method is simple, high sensitivity. Electrolysis 30 minutes
