| Abstract: | The comparative study was conducted on vacuum glass detection tube methods and the Nessler＇ s reagent spectrophotometry in respect of detection limit, precision, accuracy and sample testing. It shows that the detection limit of ammonia nitrogen by detection tube is 0. 2mg/L, the relative standard deviation of precision is 0% -5. 75% , and the recovery of standard addition of accuracy is 93% -124%. When testing various actual samples by the two methods, we have found that the relative deviation of both methods is -37. 8% -11. 8%. It is concluded that detection tube method could meet the needs of semi - quantitative test. |
