摘要
采用ICP-OES法对无锡和盐城两地的商品化石墨烯样品中镍、铁、铬、铜、钠、铝、镁、锌、锰、钙等微量金属元素的含量进行了检测,测试RSD基本都在5%以内。采用加标回收实验对测试结果进行验证,加标回收率在90.00%~106.43%之间,偏差均在10%以内。
Trace metal elements such as Ni,Fe,Cr,Cu,Na,Al,Mg,Zn,Mn,Ca in graphene were detected by ICP-OES method.The graphene samples were from Wuxi and Yancheng respectively.The RSD of the test are basicly less than 5%.At the same time,standard addition recovery experiments were used to verify the test results,recovery rate were between 90.00% and 106.43%,the deviation were all within 10%.
