Determination of Seven Metal Elements in Drinking Water by Inductively Coupled Plasma Mass Spectrometry
Objective:To establish an analytical method for the determination of seven metal elements,including aluminum,cadmium,copper,iron,manganese,lead,and zinc,in drinking water by inductively coupled plasma mass spectrometry.Method:Optimize the working parameter conditions of the instrument,select Bi,Ge,In,Sc liquid standard samples as internal standards,and sequentially analyze the reagent blank,standard series,and drinking water on the machine.Determine using inductively coupled plasma mass spectrometry.Result:By optimizing the working conditions of the instrument,suitable internal standards were selected for each of the 7 elements,overcoming the interference of mass spectrometry and non mass spectrometry during the detection process.The linear relationship of the method was good,and the detection and quantification limits met the relevant standard requirements.The recovery rates of each element were 91.4%to 104.9%,and RSD was 0.98%to 4.52%.Conclusion:This method is easy to operate,has high sensitivity,accurate results,and good reproducibility,and can be used for the analysis and detection of various metal elements in drinking water.
