The use of liquid chromatography for the analysis of metal ions in aqueous solutions and for the determination of water in organic matrices
Abstract
The value of a p-phenylenediammonium eluent in single-column ion chromatography is demonstrated. It is shown to be particularly useful for separating trivalent aluminum from common divalent metal ion interferences. The aluminum is detected with a conductivity detector. Postcolumn reaction in liquid chromatography is reviewed. The application of disodium 1-(2-thiazolylazo)-2-naphthol-3,6-disulfonate (TAN-3,6-S) to the detection of metal ions in single-column ion chromatography with a visible absorbance detector is explored. Temperature is shown to affect the retention times of divalent and trivalent metal ions in ion chromatography. Several chromatographic separations are improved by operating the system at elevated temperature. Two methods for the determination of water in organic matrices using liquid chromatography and a spectrophotometric detector are presented. Both employ a chromatographic separation by ion-exclusion. The first detection method makes use of solvatochromism, the shift in an organic spectrum which occurs as solvent polarity is changed. The second detection method uses a solid-phase postcolumn reactor containing a cation-exchange resin in the H/sup +/ form. This reactor acts as catalyst for a reaction occurring between water and two components of the mobile phase, methanol and trans-cinnamaldehyde. 122 refs., 40 figs., 16 tabs.
