在制备合成氨工艺过程所使用的低温变换、甲烷化催化剂时需对滤机洗液中的硝酸根进行检测。以往采用靛蓝或1％二苯胺硫酸溶液目视比色的半定量方法。其他如水质分析中常用的二磺酸酚比色法、马钱子硷比色法由于干扰离子和影响因素太多均不宜用作控制分析。我们使用江苏泰县无线电厂产的以7402季胺盐为交换剂,邻硝基苯十二烷醚为稀释剂的7601型液态离子交换膜电极,与上海电光器件厂产的212型饱和甘汞电
In the preparation of ammonia process used in the low temperature shift, methanation catalyst nitrate nitrate in the washing machine to be tested. In the past using indigo or 1% diphenylamine sulfate visual colorimetric semi-quantitative method. Others such as water quality analysis commonly used in the disulfonate phenol colorimetry, strychnos colorimetric method due to interfering ions and influence factors are too much should not be used as a control analysis. We use Jiangsu Tai County radio plant to 7402 quaternary ammonium salt exchangers, o-nitrophenyl lauryl ether as diluent 7601 liquid ion exchange membrane electrode, and the Shanghai Optoelectronics Factory production of 212 saturated calomel Electricity
