| Abstract: | The analytical methods of ammonia in secondary brine for production of ion-exchange-membrane caustic soda by gas sensing electrode are studied,the linearity range is determined with theoretical discussion and a lot of experiments.When the pH value is from 10.5 to 11.5,the linearity range is from 0.15 to 8.0 mg/L,the lowest limits is 0.85 mg/L,RSD is no more than 1.5%. |
| Keywords: | analysis and determination ion-exchange-memberane caustic soda secondary brine ammonia gas sensing electrode |
