| Abstract: | Ammonia nitrogen in wastewater was determined by continuous flow analysis( CFA) with online distillation and unattended system. This method showed good linearity in the range of 0. 00 to 10. 0 mg/L, and the detection limit was 0. 014 mg/L. The rela-tive standard deviations (RSD) of parallel samples were between 1. 24% and 4. 15%. The recovery rates were between 93. 0% and 108%. The precision and accuracy of this method fulfilled the requirement for the determination of ammonia nitrogen in wastewater. |
