摘要
利用Ni－Ti合金电极表面具有生物相容性和电化学特性，建立了Ni－Ti合金电极测定半胱氨酸的方法，并探讨其测定的机理，该法测定半胱氨酸的线性范围为8．25×10－7～8．25×10－5mol·L-1，相对标准偏差为6．8％。
Nickel-titanium alloy was chosen to construct the electrodes owing to its surface characteristics of biocompatibility and elecrochemical property. The Ni-Ti alloy electrodes were applied to cathodic stripping voltammetry for determining cysteine; and the mechanism of this method was discussed. While this method was used to determine cysteine, the results displayed a linear range of 8. 25×10-7 ~ 8. 25×10-5 mo;·L-1and a re1ative standard deviation of 6. 8%.
