| Abstract: |
| The potassium oxidecontent in water soluble fertilizer is determined by AA3 type continuous flow analyzer and compared with NY/T 1977-2010 method. The results show that the correlation coefficient of standard curve is 0.9995 between 0 to 400 mg /L．Compared with weight method, the results is close, below 0.23%．The RSD of ten times repeated measurement was 0.22%． the adding standard recovery rate is 98.2% - 100.6%,there is no significant difference in both methods. |
