Transient changes of mobile phase in the high-performance liquid chromatographic separation of priority pollutant phenols.
A study of the effect of cetyltrimethylammonium bromide on the separation of the eleven priority pollutant phenols is presented. Transient changes in a CTAB mobile phase produced by a sodium laurylsulphate solution plug permit the elution of hydrophobic pentachlorophenol.
