铜离子选择性电极的固体膜常用硫化铜为电活性物贸。我们合成铜的硒化物或碲化物,分别制备了性能较好的固体膜铜离子选择性电极。该电极与用硫化铜为电活性物质制备的电极相比,能斯特响应的浓度范围宽,其斜率接近理论值,响应时间、选择性以及电极的寿命等性能都较为优越。该电极正试用于污染土壤或石油化工催化剂等样品中铜的测定。 Copper ion selective electrode solid film commonly used copper sulfide electroactive material trade. We synthesized copper selenides or tellurides, respectively, prepared better performance solid film copper ion selective electrode. Compared with the electrode made of copper sulfide for the electroactive material, the Nernst reaction has a wide concentration range, the slope is close to the theoretical value, the response time, the selectivity and the lifetime of the electrode are superior. The electrode is being used for the determination of copper in samples contaminated with soil or petrochemical catalysts.
