| Abstract: | Micro amounts of calcium and magnesium in saturated high purity sodium chloride solution were determined by flame atomic absorption spectrometry after the preseparation of calcium and magnesium from matrix solution through ion exchange resin column filled with model 401 chelate resin.The parameters and operating conditions of the preseparation of calcium and magnesium from matrix solution were studied by orthogonal optimization process.The relative standard deviations of this method were 6 5% and 5 5% for calcium and magnesium,respectively.The recoveries were 99% and 94% for calcium and magnesium,respectively. |
