Three porphyrin complexes of palladium were chosen as phosphorescence sensing molecules : palladium - meso - tetra ( trimethylaminophenyl ) porphyrin ( pd - tapp ), palladium - coporphyrin ( pdcp ) and palladium - meso - tetra ( p - sulfonicphenyl ) porphyrin ( pd - tspp ). they were bound to dowex resins, and made into oxygen sensor. we detected the characteristics such as sensitivities and response times combined with flow injection analysis ( fia ) technology
選取了三種金屬
鈀的卟啉配合物:四- (三甲氨基苯基)
鈀卟啉( pd - tapp ) 、
鈀糞卟啉( pd - cp ) 、四- (對磺酸基苯基)
鈀卟啉( pd - tspp )作為磷光傳感分子,將其固定在dowex樹脂上,製成傳感器,並與流動注射分析技術( fia )結合起來,考察了其對氧
的傳感靈敏性,時間響應特性等條件。
The zircondri filin wtut rirconia wa prepared and the removing technology of the zirconia on the zirconium sdrices was obtalned. the methods of chemistry and magnetron sputtring plating were used in order to platc a palladium film, which is characteristic of self catalysis for hydrogen and the sole h - permselectivity on the clean rirconium sdrices prepared by the methods of electrochemitw and ( or ) high temperatur vacuum hydrgenization, which was firstly studied. the plating tedrilogy was obained and the surface modified zirconium membran was prepared
