Resumen:
The effect of common particle constituent oleic acid on the deliquescence phase transition of (NH4)2SO4 particles using a room temperature aerosol flow tube, FTIR detection, and SEM/EDX for particle morphology and chemical composition studies. The deliquescence relative humidity showed little dependence on the amounts of oleic acid present (?slightly lowered or not affected?) which is consistent with earlier studies of the effects of water insoluble fatty acid coatings on such phase transitions.
