Determination of calcium and magnesium in water samples by high-performance liquid chromatography on a graphitic stationary phase with a mobile phase containing o-cresolphthalein complexone
A sensitive and selective liquid chromatographic procedure for the separation and visible detection of alkaline earth metals in complex saline matrices has been developed. A mobile phase containing the selective metallochromic chelating ligand, o-cresolphthalein complexone, was used to dynamically c...
