北京交通人学硕士论文AB STRACTABSTRACT：Aiming at solving the problem in the electrochemical oxidation of ammonia wastewater,the tin and antimony electrodes based on titanium were manufactured，the effect of different manufacturing condition to the impact ofelectrochemical oxidating ammonia wastewater was researched．After researching the influential factor and optimizing the manufacturing condition，the appearance analysis and the electrochemical analysis was hold on,the electroactivated character of the electrodes was studied to provide warrant to its application in the ammonia wastewater．In this paper,the theory of electrochemical oxidation of ammonia wastewater was firstdiscussed as to choose proper electrode material to manufacture．TUSn02-Sb203、 Ti／Sn02--Sb203··Ce02electrodes was manufactured in the way of brushing and oxidation．Different factors were studied，they are：the temperature and the time of drying，the temperature and the time of pyrogenation，the time of drying and brushing, main solvent，the quantity of hydrochloric acid，the solute makeup，middle layer．Then Ti／Sn02．．5b203--Ru02 electrode was manufactured to compare with them in the aspect ofthe effect of electrochemical oxidation of ammonia wastewater．The result of the testshows：in the case of inexistence of chlorin ion，the effect of electrochemical oxidation of ammonia wastewater of the TUSn02一Sb203 electrode is beaer than theTUSn02-5b203-C如electrode’S，efficiently．When there exist 400mg／L chlorin ion,bothhave perfect effect．The optimized electrodes are chosen to take the SEM test,XPS test and electrochemicaltest．Theresult shows that：the optimized TUSn02·Sb203、 TUSn02．．Sb203··Ce02 electrodes have a compact surface and nice stability．Two kinds ofelectrodes have big exchange current density,quick reaction speed，high electrochemical oxidation performance，and that accords with the result of SEM．The overvoltage difference between oxygen evolution and chlorine evolution of optimizedTUSn02--Sb203·-Ce02 electrode was t
