“…Various HPLC methods have been tested such as thermospray LC/MS [21], Cl [22] and C18 silica based columns [23] and alumina support [24,25], Supercritical fluid chromatography also separated effectively the various nonionic surfactants [26,27]. Due to its advantageous retention characteristics zirconia support is used more and more frequently both in adsorption [28,29] and reversed phase high-performance liquid chromatography (HPLC) [30], in affinity [31], ion-exchange [32] and hydrophobic interaction chromatography [33].…”

The retention behaviour of nonylphenyl ethylene oxide oligomer surfactants was determined on polyethylene-coated zirconia high-performance liquid Chromatographic (HPLC) support using methanol-water mixtures as eluents. The logarithm of the capacity factor decreased linearly with increasing concentration of methanol in the eluent proving the regular retention behaviour of the HPLC system. The retention capacity of the polyethylene-coated zirconia was lower than that of traditional octadecylsilica stationary phase. The retention of nonionic surfactants increased with increasing number of ethylene oxide groups in the molecule. It was established that polyethylenecoated zirconia support can be successfully used for the analysis on nonionic surfactants.
