ICP-AES法测定植物染发剂中重金属
Journal of Yantai University(Natural Science and Engineering Edition)(2017)
Abstract
研究了湿法消解处理试样和利用电感耦合等离子体发射光谱(ICP-AES)法同时测定植物染发剂中As、Cd、Co、Cr、Cu、Pb等重金属元素含量.结果表明:湿法消解预处理试样,180℃加热消解,ICP-AES激发功率1 151 W、雾化器压力310 kPa、溶液分析流量1.85 mL/min、辅助气流量1.0 L/min,测得试样中重金属元素的含量,此方法检出限为0.012 ~11.2 μg/L,线性范围均为0~200 μg/L,加标回收率在80.5 ~ 104.0%之间,相对标准偏差0.91 ~8.71%.该方法简便快捷,结果准确可靠,适合同时测定染发剂中多种重金属元素含量.
