在ｐＨ＝８．８４的ＮＨ４Ｃｌ－ＮＨ３·Ｈ２Ｏ缓冲溶液中，酪氨酸能够吸附在玻璃电极表面．当阳极溶出时，会产生一个灵敏的氧化峰，其峰电流和酪氨酸的浓度在１．０×１０－５～８．０×１０－８ｍｏｌ／Ｌ范围内成线性关系，最小检出限可达１．０×１０－８ｍｏｌ／Ｌ．本文研究了电极反应机理，找出了测定酪氨酸的最佳实验条件，建立了测定酪氨酸的灵敏的分析方法
In NH4Cl-NH3 · H2O buffer solution of pH = 8.84, tyrosine can adsorb on the surface of glass electrode. When the anodic dissolution, will produce a sensitive oxidation peak, the peak current and tyrosine concentration in the range of 1.0 × 10-5 ~ 8.0 × 10-8mol / L linear relationship between the minimum detection limit Up to 1.0 × 10-8mol / L. In this paper, the electrode reaction mechanism was studied, the best experimental conditions for the determination of tyrosine were found, and a sensitive analytical method for the determination of tyrosine was established
