A quantitative ion chromatographic analytical method for the determination of fluorine in fluorocarbon coatings is proposed. The extraction of the anions from the samples was performed using potassium hydroxide after centrifugation drying to dissolved at preference temperature. Using H column to remove large amounts of potassium ions in the solution。In paper describe the observed limits of detection and of quantitation in mg kg-1 and the mean relative standard deviation in percent This method is simple operation, less interference factors, fast analysis speed, the determination results accurate and reliable, with good repeatability and reproducibility.
