| 摘 要： | 本文采用流动注射分析，用亚硝基铁氰化钠的碱性缓冲液(pH＝12)为显色剂，测定乙酰半胱氨酸的含量。乙酰半胱氨酸在浓度40～200×10－6g／ml内线性方程为Y＝5.17×104X－1.8×106(r＝0.9991)；样品测定平均回收率为99.14％(RSD＝1.3％，n＝5)。本法具有分析速度快(180次／h)、选择性好等优点，适用于大批量样品的分析和生产监测。

| Abstract: | A new method was introduced for determination of N-Acetyl-L-cysteine with sodi-um nitroproussde in the buffer solution(pH=12)by flow injection analysis. The calibration graphfor N-acetyl-L-cysteine is linear from 40× 10-6 to 200 × 10-6g/ml(Y=5. 17 × 104X-1.8 × 106,r=0. 9991,n=5). The rate of recovery was 99. 14%(RSD=1.3%,n=5). The method with higherspeed(180times/h)and bettter selection is suitable for determination of large samples and produc-tion control. |
