We all know that coal combustion produces too much NOX in the boiler which is for electricity generation in the thermal power plant, which will cause serious environment pollution. We need to denitration coal processing, but ammonia would escape at the same time, therefore the research on ammonia escape law in the denitration process is particularly important.

In this paper, we summarized the ammonia escape law in the denitrification process through the detection of ammonia recovered from the power plant dust. Nessler's reagent colorimetry, which is a kind of national standard method to assay the content of trace ammonia in the air, is used to detect ammonia. Spectrophotometer is used to determine the absorbance of the best pretreatment test specimen in 400 and 420nm wavelength. Pretreatment scheme is the optimal scheme which is determined by comparing its respective advantages and disadvantages via using several different acid reagents. The emphasis on this subject is to determine the interference range of various interfering ions in the process of ammonia determination, and then explore a method to remove interference, so as to make the determination results to a certain degree of reliability at last.
