| Abstract: | The contents of six elements（Fe,Mg,Mn,Cu,Al and Zn） in red jujube from different areas were determined by ICP-AES.The red jujube samples were digested by microwave with HNO3-H2O2 solution as reagent,the conditions of pretreatment for samples were discussed.The reliability of analitical data was checked by additional standard recovery test.Under the optimal conditions,the detection limits of the six elements were in the range of 0.0005—0.0100μg·mL-1.The recoveries were in the range of 90.0%—103.6%,with the RSD≤4.2%.The method is easy,rapid and accurate. |
