摘要
Barium sulfate scale is dissolved by contacting it with an aqueous solution of: a bicyclic macrocyclic polyether in which the intramolecular cavity or cript is preferentially receptive to the cations of alkaline earth metals, at least a catalytically effective proportion of an alkali metal salt of an organic acid, and enough dissolved alkaline inorganic alkali metal or ammonium compound to provide a solution pH of at least about 8.
