Determination method for content of polyoxyethylene octylphenol ether and polyoxyethylene nonyl phenyl ether in water-based adhesive

The invention relates to a determination method for content of polyoxyethylene octylphenol ether and polyoxyethylene nonyl phenyl ether in a water-based adhesive, and the method comprises the steps of sample solution preparation, liquid chromatography analysis, determination result calculation and the like. The optimized detection method has the advantages of short detection time, simple operation, high sensitivity, high recovery rate, good repeatability and the like. The chromatographic conditions of the method can well separate the chromatographic peak of the polyoxyethylene octylphenol ether and polyoxyethylene nonyl phenyl ether and the chromatographic peak of impurities, the method has good correlation, the limits of detection are respectively 0.34mug / gand 0.93 mug / g, the average recovery rates are respectively 96.8% and 81.9%, the average relative standard deviations of the sample test results are respectively 5.60% and 3.13%, and the method is high in recovery rate and better in repeatability.
