The method of testing metal ions in water by MPT- AES has been studied. Through experimental data,the influence of carrier gas flow, support gas flow and microwave power to emission strength of metal ions of Na,Mg, Ca, Cu, Fe, Sn, Pb, Ag are analysed. And the experimental conditions are optimized. The optimum conditions to get the working curves, the detection limit, RSD(less than 5%) and recovery(90%- 101%)of the 8 kinds of metalions have been obtained.This apparatus analysis method can work accurately,quickly and conveniently.The detection limit is very low. It can be used for detecting metal ions in environmental water and processed water.
Key words: metal ions; microwave plasma torch; atomic emission spectrometry
