Design And Synthesis Of Aromatic Sulfonic Acid Bipyridylamine Polymer And Study On The Adsorption Properties Of Congo Red

In this paper,the hydrothermal?solvothermal?reaction of Zn?II?/Cd?II?salts and synthesized N,N'-bis?pyridin-4-ylmethyl?ethane-1,2-diamine?L1?and N,N'-bis?pyridin-3-ylmethyl?ethane-1,2-diamine?L2?ligands gives rise to twelve new bis?pyridyl?amine Zn/Cd-based complexes with different arenesulfonates counter-anions.These complexes are characterized by the infrared?IR?spectroscopy,thermogravimetric?TG?analyses,photoluminescence?PL?,powder and single crystal X-ray diffraction.The different coordination modes of L1 and L2 and the synergistic effect of different arenesulfonate anions make these twelve complexes present diverse topological structures.In addition,the large conjugated system of 1,5-NDS-contained complexes exhibit strong solid state emission.Especially,the CR adsorption properties of the two acid-base and thermal stable complexes,[Cd₄?L2?₄?H₂O?₈?NDS?]_n·3n?NDS??11?and[Cd?L2??BS?₂]_n·2nH₂O?12?,are also studied in details in this thesis,such as adsorption kinetics,isothermal adsorption models,adsorption thermodynamics,adsorption mechanism,reusability,as well as the influence of pH on adsorption capacity and the dosage selection of adsorbent.Moreover,the photoluminescence?PL?technology is firstly utilized to analyze the adsorption behavior of complexes 11 and 12 to CR.
