【Abstract】 We studied the analytical condition for Ag with P E3030B atomic absorption spectrophotometer.In order to determine microamount Ag in the super pure Hydroperoxide or absolut Alcohol,we adropted the concentration impurety in sample by means of the evaporation and the standard addition method obtained the satisfactry results.By means of this method,the contamination can be diminished in analytical process.The detection limit is 0.066 ng/ml and precision is 3.76% .更多还原
