| Abstract: | A method for the simultaneous determination of arsenic content in rice by microwave digestion-differential potentiometric stripping analysis was established.The results indicated that the peak currents were linear with the concentration of arsenic in the range from 0 ng to 200 ng,the recovery was 93.2%~105.4%,and the relative standard deviation was 2.35%.This method is rapid,simple,accurate and reliable. |
