• A simple, selective and reproducible method for the potentiometric determination of some aliphatic aldehydes is described. The method is based on oxidation of the aldehydes with silver oxide packed in a column. The formed silver salts of the fatty acids are eluted with water and the silver ion concentration is determined with a silver/sulfide ion-selective electrode using either a calibration graph or a standard addition technique. The effects of experimental variables and the interference of other organic functional groups are investigated. Samples containing up to 5.0 mg aldehyde are analyzed with an average recovery of 98.5% and 98.4% using the proposed techniques, respectively.
