A method of inhibiting scale in an industrial water system includes the steps of dosing the industrial water system with a water treatment polymer comprising at least 10 mol % of carboxylic acid monomer and a quaternized naphthalimide fluorescent monomer as disclosed herein, and then monitoring the fluorescence of the water system. The polymers are also useful for flocculation and coagulation in wastewater treatment.
在工业水系统中抑制水垢的方法包括以下步骤:向工业水系统投加一种水处理聚合物,该聚合物包括至少10摩尔%的羧酸单体和一种苯并二酰亚胺荧光单体,然后监测水系统的荧光。这些聚合物还可用于污水处理中的絮凝和凝聚。
