Three kinds of amide polymer organic amines with different structure,including nonionic polyacrylamide(NPAM),polysuccinimide(PSI)and polypotassium aspartate(PASP-K),are used as denitrification agent,and their thermal decomposition process is studied through thermogravimetric and temperature programmed mass spectrometry,and their denitrification performances at high-temperature are investigated.It is indicated by the results that the thermal stabilization of the three kinds of amines is PSI＞PASP-K＞NPAM,and their denitrification performance is in the order of PASP-K＞NPAM＞PSI,which is related to the rate and amount of ammonia generated by the decomposition of the amines.Among them,PASP-K has the best denitrification effect because it has better thermal stabilization and can generate more decomposed ammonia amount.Therefore,the suitable polymer denitrification agent should have higher ammonia decomposition amount and suitable decomposition rate.
