| 摘 要： | 基于硫酸庆大霉素对鲁米诺在铂电极上弱的电氧化发光信号的强增敏作用与流动注射技术的结合，建立了一种测定硫酸庆大霉素的电化学发光分析新方法。该法测定硫酸庆大霉素的检出限为8.0×10-10 g·mL-1，线性范围为1.2×10-9～4.0×10-6 g·mL-1，相对标准偏差为2.0%(n =11)。该法简单、快速、灵敏，已成功地用于注射液中硫酸庆大霉素的测定。

| Abstract: | A new flow injection electrogenerated chemiluminescence (ECL) method for the determination of genyamicin sulfate was developed. The method is based on the sensitizing effect of genyamicin sulfate on the weak ECL signal of electrochemical oxidation of lumninol on the platinum flake electrode in the medium of Na2B4O7. The experimental conditions that influence the ECL intensity were investigated and optimized. Under the optimum conditions, the ECL response is in the range of 1.2 x 10(-9) - 4.0 x 10(-6) g x mL(-1) genyamicin sulfate with a detection limit of 8.0 x 10(-10) g x mL(-1). The relative standard deviation is 2.0%. This method was used to determine genyamicin sulfate in injection samples with satisfactory results. |
