摘要：

Alkylphenol ethoxylate surfactants can be separated by high-performance liquid chromatography on Spherisorb silica using pH 3 buffer-acetonitrile eluents. Increasing the organic content of the eluent leads to more rapid elution, but evidence is produced to suggest that hydrogen bonding is the chief retention mechanism and the separation is an example of a ''pseudo-reversed-phase'' process.
