| 摘 要： | 甘氨酸和Ｐｄ（ＮＨ３）２Ｃｌ３组成镀液，用于钯和葡萄糖氧化酶（ＧＯＤ）的电化学共沉积以制备金属化酶电极、ＵＶ／Ｖ光谱实验表明甘氨酸能与Ｐｄ＾２＋离子发生络合作用，并使镀液在一定ｐＨ范围内具有较稳定的化学组成。伏安法实验证实甘氨酸的存在降低了Ｐｄ的沉积电位，有利于防止钯氢化合物的形成，讨论了钯和ＧＯＤ电化学共沉积的合适条件。

| Abstract: | Glycine and Pd(NH 3) 2Cl 2 consist of a solution for the electrochemical codeposition of Pd and glucose oxidase (GOD) to prepare a metallized enzyme electrode. The experiments by UV/V spectroscopy show that the complexing of Pd ion with glycine can occur, which makes the plating bath has relatively stable chemical composition in a certain pH range. The voltammetric experiments indicate that the presense of glycine decreases the potential of Pd deposition ,facilitating to prevent the formation of palladium hydride. The appropriate conditions for the electrochemical codeposition of Pd and GOD are discussed. |
