Abstract
A novel water soluble fluorescent monomer,N-(2-acrylaminoethyl)-4-methoxy-1,8-naphthalene diacylimide(Ⅲ),was synthesized by a three-step reaction from 4-bromo-1,8-naphthalic anhydride and ethylenediamine.A novel acrylic acid copolymer(1) containing fluorescent group was prepared by polymerization reaction of Ⅲ with acrylic acid and maleic anhydride.The structures were characterized by IR,TG-DTA and SEM.The fluorescence property and scale inhibition of 1 were investigated.The results showed that the relationship of fluorescent intensity and concentration of 1 was linear,the correlation coefficient(R) was 0.998 5,the lower limit of detection was 1.0×10-2mg·L-1.The scale inhibition ratio of CaCO3 was 93.5% at 20 mg·L-1.The capacity of dispersing iron oxide was pretty good.It was found that by electronic microscopy 1 has obvious effect on CaCO3 scale with regard to its dispersion and crystal lattice distortion capacities.
