摘　　要：在磷酸介质中,过氧化氢存在下,加入少量Cu2+的盐酸异丙肾上腺素试液经80℃水浴加热处理后与高碘酸钠反应产生强烈的化学发光。据此,结合流动注射技术建立了一种测定盐酸异丙肾上腺素的化学发光分析新方法。方法的线性范围为1.0×10-9~7.0×10-7g/mL,检出限为4.0×10-10g/mL,相对标准偏差为3.0%(1.0×10-8g/mL盐酸异丙肾上腺素,n=11)。该法用于注射液中盐酸异丙肾上腺素的测定,回收率为97%~103%。After isoprenline hydrochloride is heated in a water-bath （80℃） with Cu^2＋, it reacts with sodium periodate and hydrogen peroxide in the acidity medium to produce chemiluminescence signals. Based on this fact, a new chemiluminescence method for the determination of isoprenline hydrochloride with flow injection technique has been established. The linear range is 1.0×10^-9-7.0×10^-7g/mL. The detection limit of isoprenline hydrochloride is 4.0 × 10^-10 g/mL and the relative standard deviation（RSD） is 3.0% （1.0 × 10^-8 g/mL, n = 11）. The method has been applied to the determination of isoprenline hydrochloride injection with satisfactory results.
