Determination of Metal Ion Content and Maintenance Measures in Tarim River of Xinjiang by ICP-OES
The water body of Tarim river in Xinjiang is rich in potassium,sodium,calcium,magnesium and other high concentration metal ions.In this paper,ICP-OES method is established to determine the content of potassium,sodium,calcium and magnesium in Tarim river in Xinjiang,and the standard curve solution is prepared by weighing method.Compared with the traditional pipetting method,the dilution multiple calculated by weighing method is more accurate.The linear correlation coefficient of the standard curve is better.The detection limit,precision and accuracy of the method are tested by vertical observation,and the experimental results are good,indicating that the maintenance measures of ICP-OES sampling system are effective.
