摘要
提出了由两束碳纤维和Ag/AgCl丝制备组合电极的方法和处理方法,系统地讨论了电化学条件对组合电极响应的影响,利用该组合电极,测定国家标准物质锌(CRMGBW02703)中微量钢,相对标准偏差2.0%.相对误差0.5%,结果令人满意.
The preparation and treatment of composite electrode made from bundle of double carbon fibres with Ag/AgCl wire were developed,and the effect of electrochemical conditions on voltammetric response of composite electrode is discussed. The electrode was used to determine the copper trace in Zinc (CRM GBW 02703) and a satisfactory result was obtained,i. e. RSD 2. 0% and relative error 0. 5%.
