| Abstract: | The thesis studied the new method for oscillographic titration of the determination of nitrogen content in Ammonium. Oscillographic titration is conducted on NH 4 with Na-TPB method,then calculate the nitrogen content. Compared with standard methods,choose Unpoisonous Tetrathyl ammonium chloride titrant,the above on needs one distillation absorption and indicator.It has the advantages of being easy and quick in operation, and the determination result is accurate and reliable. - |
