| Abstract: | Determining potassium,sodium calcium and magnesium in surface water with air-acetylene flame atomic absorption spectrophotometry,both deionization agent,used to determine potassium and sodium,and releasing agent,used to detemine calcium and magnesium,were mixed.The mixed solution used to determine the four elements in surface water continuously.This method is simple and fast.Its accuracy and precision were as well as the old method. |
| Keywords: | flame atomic absorption spectrophotometry determination surface water potassium sodium calcium and magnesium |
