| Popis: | Whisker-walled open tubular columns were coated with either manganese(II)chloride or cobalt(II) chloride. These inorganic salt coated columns were employed to study the interaction of these sorbents with aromatic hydrocarbons that possessed varying π-electron density and alkyl substitution. Halogenated aromatic hydrocarbons eluted according to boiling point. whereas the retention of alkyl-substituted benzenes increased with alkyl chain length and the degree of substitution. The open tubular columns provided increased performance compared to packed columns containing these inorganic salts. The dynamic procedure was considered a practical method for coating the whisker-walled columns The effects of column dimensions, adsorbent concentration and sample capacity were studied. |
