摘要
IR spectra of propylene glycol solutions in water were measured in the region of the first overtone of water. The inhibition efficiency of calcium sulfate was determined as a function of the pH value and propylene glycol content of water. A concept is suggested for taking into account the water-complexone interaction in inhibition of calcium sulfate crystallization with phosphonic acids.
