| Abstract: | The techniques for soil sample pretreatment,such ultrasonic extraction and water bath extraction as microwave-assisted extraction were comparatively studied for inorganic arsenic in the standard substances of national level soil by HG-AFS.The influencing factors of solvent,extraction time,and the volume of extraction solvent on the efficiency were discussed.Compared with the ultrasonic extraction and water bath extraction method,the microwave-assisted extraction was time saving and more efficient. |
