Description

Micellar electrokinetic chromatography (MEKC) was used preliminarily to evaluate the simple, simultaneous analysis of nonylphenol polyethoxylates (NPnEOs) and their degradation products (NPnEOs: n=number of ethoxy units; 1-18, nonylphenol, nonylphenoxyacetic acid and nonylphenoxyethoxyacetic acid) in water. A 1000 ml water sample was loaded into a cartridge packed with Oasis HLB, copoly (N-vinylpyrrolidone-divinylbenzene) . After concentrating the eluate (104times), the concentrate was subjected to MEKC with sodium deoxycholate as the micelleforming reagent. More than 82% of the analytes spiked to the ma and Neya river waters were recovered with good reproducibility (relative standard deviation=3.0-15%) . Thus, the application of this simple method to the simultaneous analysis of nonylphenol polyethoxylates and their degradation products in water is promising, though further improvement is needed.
