Abstract:
A novel water soluble fluorescent monomer,4-(N′-methyl-1-piperazinyl)-N-methyl-1,8-naphthalimide allyl chloride quaternary ammonium salt(FM) is synthesized from 4-bromo-1,8-naphthalic anhydride and methylamine.Its structure is characterized by IR,1H NMR and MS.The acrylic acid / hydroxypropyl acryate copolymer containing fluorescent group(FM-AA-HPA) is prepared by copolymerization of FM,acrylic acid(AA) and hydroxypropyl acryate(HPA).The effects of FM-AA-HPA on fluorescence and scale inhibition are researched.The results show that the wavelength of the excited and the emitted spectrum of FM-AA-HPA are 399 nm and 531 nm respectively,and the shapes are symmetric as mirror images.The relationship of fluorescent intensity and concentration of FM-AA-HPA is linear.The correlation coefficient(R) is 0.997 8 and the limit of detection is 0.95 mg·L-1.By the static method,the scale inhibition ratio of Ca3(PO4)2 is 85.4% when the copolymer concentration is 20 mg·L-1;the scale inhibition ratio of CaCO3 is 70.9% when the copolymer concentration is 15 mg·L-1;the scale inhibition ratio of CaSO4 is 86.5% when the copolymer concentration is 15 mg·L-1;the ability of stabing Zn2+ ion is good.The results from SEM show that the copolymer has high performance of scale inhibition on lattice distortion of CaCO3.
