我们都知道火电厂发电所用的锅炉内煤燃烧后将会产生过多的NOX，会对我们的环境造成严重污染，我们需要对煤进行脱硝处理，但是于此同时又会逃逸出氨气，因此研究脱硝过程氨逃逸的规律就显得尤为重要了。 本文通过对从电厂中取回的除尘灰中的氨进行检测，总结出脱硝过程中氨逃逸的规律。在测定氨的方法上选用了国标中测定空气中微量氨的纳氏试剂比色法，使用分光光度计在波长400、420nm下对最佳预处理后的试样进行吸光度测定，预处理方案是使用几种不同的酸性试剂，比较各自优缺点后确定最佳方案。在该课题中最为重点的就是在测定氨的过程中确定各种干扰离子的干扰范围，然后探究出排除干扰的方法，最终使测定出来的结果具有一定的可靠性。 |

【译】 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. |
