Abstract
The chromatographic behavior of alkali and alkaline-earth metals on a column packed with silica with attached lysine groups was studied with the use of dilute solutions of perchloric acid as eluants and indirec t conductometric detection. The optimum separation of alkali and alkal ine-earth metal cations is obtained when a 3 x 10(-3) M solution of pe rchloric acid is used as a mobile phase. The developed procedure was u sed to analyze several samples of water from a water supply line and a well.
