  • Evaluation of Micellar Electrokinetic Chromatography for Simultaneous Analysis of Nonylphenol Polyethoxylates and Their Degradation Products in Water

抄録

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.
