SummaryA pure silica gel (Pia Seed 5S-60-SIL), synthesized by the hydrolysis of pure tetraethoxysilane [Si(OCH2CH3)4L was applied as a cation-exchange stationary phase in ion chromatography with indirect photometric detection for common mono-and divalent cations (Li +, Na +, NH4 +, K +, Mg 2+ and Ca 2+) using various protonated aromatic monoamines (tyramine [4-(2-aminethyl)phenolL benzylamine, phenylethylamine, 2-methylpyridine and 2,6-dimethylpyridine) as eluent ions. When using 0.75 mM tyramine-0.25 mM oxalic acid-l.5 mM 18-crown-6 (1,4, 7,10,13,16-hexaoxacyclooctadecane) at pH 5.0 as the eluent, excellent simultaneous separation and highly sensitive detection at 275 nm for these mono-and divalent cations were achieved on the Pia Seed 5S-60-SIL column (150 x 4.6 mm I.D.) in 20 min.
