Retention of Some Simple Organic Cations on an Anion Exchange Column

摘要

The retention behavior of a homologous series of phenyl-substituted alkylammonium ions on a styrene-divinylbenzene copolymeric anion exchange column with acetonitrile - aqueous solution mobile phase was investigated. As the concentration of eluent anion increased, the retention of eluite cation was increased. This relationship showed good linearity in log-log coordinates. The methylene selectivity of members of a homologous series of eluite cations was also studied.
