WebAt a BOD:N ratio of 100:4.9, ammonium discharge was significantly greater (1.8 mg/L) than at the lower nitrogen levels (0.04 - 0.18 mg/L). Phosphorus behaviour was more variable, however significantly more phosphorus was discharged at the lowest nitrogen level than at the highest (p<0.05). WebThe kjeldahl nitrogen in the sample is first converted to ammonia by metal-catalyzed acid digestion. The resulting ammonia is then separated from the sample by distillation. The ammonia released is captured in a dilute sulfuric acid solution. A procedure is given for removal of the ammonia present in the sample prior to digestion.
