摘要：

In order to conveniently monitor the concentration of poly(aspartic acid) (PASP) used as a green scale inhibitor in cooling water systems, and to improve calcium phosphate inhibition, carbazole and hydroxy groups-tagged PASP (CHGTPASP) was synthesized by ring-opening reaction of N-(2,3-epoxylpropyl)carbazole (EPC) with partially ethanolamine-modified polysuccinimide (PEAMPSI) followed by alkaline hydrolysis. CHGTPASP has good Ca-3(PO4)(2) and CaCO3 inhibition and its fluorescence intensity (Fi) is good linear to concentration. These multifunctional properties are of importance in industrial water processing economically and environmentally.
