摘要
目的:建立透析液中K+、Na+、Ca2+、Mg2+离子的含量测定方法。方法:采用火焰原子吸收分光光度法测定透析液中K+、Na+、Ca2+、Mg2+离子的含量。结果:K+、Na+、Ca2+、Mg2+离子的线性范围分别为0.1μg～1.8μg(r=0.9957);20μg～100μg(r=0.9973);1μg～5μg(r=0.9997);0.2μg～1.0μg(r=0.9897);加样回收率(n=6)分别为102.8%、97.1%、101.2%、108.3%;RSD为1.5%、2.3%、2.6%、2.5%。结论:该方法准确、可靠,具有良好的重复性和稳定性,可用于透析液中K+、Na+、Ca2+、Mg2+离子的含量测定。
Objective： to establish a method for the determination of K^＋、Na^＋、Ca^2＋、Mg^2＋ ions in Dialysis Fluid. Methods： the flame Atom Absorption Spectrometer were used to determine K^＋、Na^＋、Ca^2＋、Mg^2＋ ions Concentrations in Dialysis Fluid. Results： K^＋、Na^＋、Ca^2＋、Mg^2＋ions had good linearity in the ranges of 0.1μg～1.8μg（r=0.9957）, 20μg～100μg（r=0.9973）, 1μg～5μg（r=0.9997）, 0.2μg～1.0 μg（r=0.9897）,respectively; the average recoveries were 102.8%, 97.1%, 101.2%, 108.3%; RSD were 1.5%, 2.3%, 2.6%, 2.5%, respectively. Conclusion： the developed method is accurate with high repeatability, which is helpful for the determination of K^＋、Na^＋、Ca^2＋、Mg^2＋ions in Dialysis Fluid.
