摘要： A method is disclosed to inhibit scale formation in aqueous systems whereby a threshold amount of a scale inhibiting agent, represented by an aminoacid alkylphosphonic acid, is added to the aqueous system. The aminoacid moiety can be represented by α-species or by species having, at least, two or more carbon atoms between the carboxylic moiety and the amine group. These aminoacid based inhibitors exhibit unusually superior performance and system acceptability compared to leading state-of-the-art inhibitors.
