| Abstract: | Using microwave plasma torch (MPT) as excitation light source, argon as support gas, the sample solution was introduced into a pneumatic nebulization system by the standard addition method. The determination of magnesium,calcium and sodium in the mineral water by microwave plasma torch atomic emission spectrometry (MPT-AES)was studied. By observing the experimental conditions(including HCl concentration in the sample solution, microwave forward power,carrier gas flow rate, support gas flow rate and oxygen shield gas flow rate), the effect of the easily ionized elements (EIES) on the calcium and magnesium emission signal was investigated in detail. The result shows that this determination method is effective to determine the quality of mineral water in its accuracy, easy operation, high automation and low operation cost. |
