Separation and visible detection of alkaline earth metals on a polymeric reversed-phase column with a mobile phase containing a selective colour-forming chelating ligand
A polystyrenedivinylbenzene reversed-phase column has been used in conjunction with a mobile phase containing o-cresolphthalein complexone for the separation and visible detection of alkaline earth metals. Retention is achieved due to the formation of a dynamically coated chelating stationary phase....
