| Abstract: | 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. |
