离子注入是一种新技术，可按人们的意愿和需要，将不同的离子注入不同的基体电极表面，制成具有催化活性强、稳定性高、重现性好等特点的修饰电极。作者研究了离子注入钴和注入镍的玻碳电极在０．１ｍｏｌ／Ｌ ＨＡｃ－ＮａＡｃ缓冲溶液中硝基苯的行为及测定。结果表明，该电极有较高的催化活性、稳定性和重现性。其测定的线性范围对于注入镍和注入钴的玻碳电极分别为２．０×１０－５ ～４．0 ×１０－4 和６． ０×１０－5～８．0 ×１０－4 ｍｏｌ／Ｌ，用于分析纯苯胺中微量的硝基苯的测定，回收率在91.0％～１０８％之间。
Ion implantation is a new technology, according to people’s wishes and needs, different ions will be injected into different substrate electrode surface, made of catalytic activity, high stability, good reproducibility and other characteristics of the modified electrode. The authors investigated the behavior and determination of nitrobenzene in 0.1 mol / L HAc-NaAc buffer solution by ion implantation of cobalt and nickel-infused glassy carbon electrodes. The results show that the electrode has high catalytic activity, stability and reproducibility. The linear range of the measurement was 2.0 × 10 -5 to 4.0 × 10 -4 and 6 for the cobalt-carbon electrode into which nickel and cobalt were implanted, respectively. 0 × 10-5 ~ 8.0 × 10-4 mol / L for the determination of trace aniline in nitrobenzene, the recovery was between 91.0% ~ 108%.
