| Abstract: | Gold in water were determined directly by inductively coupled plasma-atomic emission spectrometry.The wavelength selection and the elimination of the interference from coexistent elements on the determination of the gold element was discussed.Experiments showed that under the best instrument conditions and determination conditions,the detection limit is 0.008 mg/L.The quantitative analysis results showed that the relative standard deviations(RSD)are 4.28%~1.44%,and recovery rates are 96%~104%.The method is simple and quick to operate. |
