Organophosphorus compounds and sulphoxides as column activators in adsorption chromatography

  • P. Markl
Originals

Summary

It is shown that solvents 10−4–10−3M in tri-n-butylphosphate (TBP), tri-n-butylphosphine oxide (TBPO) or di-n-butylsulphoxide (DBSO) can be used for solvent generated adsorbent modification in liquid-solid chromatography. TBP and — to a lesser degree — TBPO or DBSO act as column activators for the retention of aromatic carboxylic acids and phenols on hydrophobic bonded phases from aqueous solutions. Significant differences in selectivity and magnitude of capacity factors are observed.
