摘　　要：目的:建立海藻酸钙敷料中钙、铁、钠离子含量的测定方法。方法:以镧溶液为释放剂,采用火焰原子吸收分光光度法定量测定海藻酸钙敷料中Ca2+离子及Na+、Fe3+离子含量。结果:Ca2+、Na+、Fe3+离子的线性范围2.0μg/mL^10.0μg/mL(r=0.9999),0.1μg/mL^0.5μg/mL(r=0.9996),3.0μg/mL^7.0μg/mL(r=0.9996);加样回收率(n=6)分别为102%,99.0%,97.5%,RSD分别为2.5%,2.1%,1.2%。结论:该方法准确、可靠,重复性良好,可用于海藻酸钙敷料中钙、铁、钠离子含量的测定。Objective： to establish a content determination method for Calcium Alginate Dressing. Methods： A flame atomic absorption spectrometry were used to determine Ca^2＋, Na^＋, Fe^3＋ ions Concentrations in the Calcium Alginate Dressing with Lanthanum solution as releasing agent. Result： Ca^2＋, Na^＋, Fe^3＋ ions had good linearity in the ranges of 2.0μg/mL-10.0μg/mL（r=0.9999）; 0.1μg/ mL-0.5pg/mL（r=0.9996）; 3.0μg/mL-7.0μg/mL（r=0.9996）, respectively; the average recoveries were 102%, 99.0%, 97.5%; RSD were 2.5%, 2.1%, 1.2%. Conclusion： This method is accurate with good repeatability, which can be used for the determination of the Ca^2＋, Na^＋, Fe^3＋ ions concentrations in the Calcium Alginate Dressing.
