On Inhibition of Calcium Sulfate Crystallization with Phosphonic Complexes

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.
