Study On The Lanthanide Ions Fluorescence And The Metal Ions Absorption With Copolymer Contaning Carboxylic Acid Group

In this thesis,copolymer of poly(styrene-co-n-caprylamide maleic acid)(PSCMA,defined as HL)and aniline-g-poly(styrene-co-maleic anhydride)(AP/SMA,defined as HL)have been synthesized and applied to sensitize rare earth luminescence and adsorb metal ions.The main content of this thesis contains four parts as follows:1.We have made a literature review on the development and research progress of sensitize rare earth luminescence and adsorb metal ions with copolymer.2.Copolymer of poly(styrene-co-n-caprylamide maleic acid)(PSCMA,defined as HL)and its lanthanide complexes LrnL3-6H2O(Ln=Eu and Tb,)(Fig.a)had been synthesized and characterized by elemental analysis,X-ray diffraction(XRD),fourier transform infrared spectra(FT-IR),UV-spectrophotometer,fluorescence spectrophotometer and thermal analysis(TG-DTA).3.The absorption behavior of aniline-g-poly(styrene-co-maleic anhydride)(AP/SMA)towards Ln3+ ions(Ln=La and Eu)has been studied in detailed.Moreover,the copolymer and its lanthanide(?)ions complexes Ln-AP/SMA(Ln=La,Eu,Tb and Yb)(Fig.b)were characterized by elemental analysis,fourier transform infrared spectra(FT-IR),1H NMR analysis,fluorescence spectrophotometer,thermal analysis(TG-DTA)and differential scanning calorimetry(DSC).4.The absorption behavior of copolymer of PSCMA and AP/SMA towards Cu2+ ion,in different pH and adsorbent,was studied in detailed,meanwhile,the structure of Cu-PSCMA and Cu-AP/SMA complexes was determined(Fig.c).Also,the process of metal separation as was shown in Fig.d.
