Rapid Determination of Polyoxyethylene Octylphenol Ether in Leather by RP-HPLC

A rapid and simple method was developed for measurement of polyoxyethylene octylphenol ether residue in leather by reversed-phase high performance liquid chromatography.The pretreatment conditions such as extrac-tion method, temperature and time were optimized.The quantitation limit range was 2~200 μg/mL.The spiked recoveries were in the range of 96.3%~103.8%, and the relative standard deviations ( RSDs) varied from 2.7%to 5.2%.The method is very simple to handle with and has sensitive and rapid response, a useful and efficient one for OPEO-10 residue determination in leather products.
