| Abstract: | Study on the analysis method of 16 impurity elements in silver ingot, silver powder,silver paste in the de- termination of inductively coupled plasma atomic emission spectrometer. Through the experiment, it sampled the pro- cessing and digestion method, established the best working conditions of instrument, the optimization test on acidity, matrix interference, interference of coexisting elements. The detection limit, precision and accuracy test show that the method is accurate and fast, suitable for routine analysis. |
