Abstract:The analysis methods of five main inorganic nitride including ammonia,notrate,nitrite,cyanide(including free cyanide and conplexing cyanide),thicyanate and total nitrogen(T-N) were discussed.In addition,the content of the five inorganic nitrides and total nitrogen in the coking waste waterwas analyzed.The experimental results showed that ammonia,nitrate,nitrite and thiocyanate were the main source of total nitrogen in the coking waste water.The conversion efficiency of ammonia and nitrite into T-N in the analysis process was more than 95%,while that of the thiocyanate and complexing cyanide was only 88% and 75%.In the coking waste water,the content of T-N was less than the total results of five main inorganic nitride,and the analyzing effciency of T-N was about 83% to 101%.
