摘要： 建立了同时测定爽身粉中的铅、砷、汞和硼4种禁限用物质的电感耦合等离子体发射光谱法(ICP-OES)。采用微波消解处理样品,用电感耦合等离子体发射光谱法同时测定4种禁限用物质。结果表明,4种元素分别在0.5~6,0.05~0.5,0.02~0.2和2~20 mg·L-1范围内时,各元素响应值与质量浓度呈良好的线性关系,相关系数均大于0.999,样品中各元素的加标回收率在88.0%~108.8%。将该方法应用于爽身粉中禁限用物质的快速筛查,结果满意。

Abstract: A method for the simultaneous determination of the forbidden and restricted elements lead (Pb),arsenic (As),mercury (Hg) and boron (B) in talcum powder by inductively coupled plasma optical emission spectroscopy (ICP-OES) was established.After being pretreated with microwave digestion,the four forbidden and restricted elements in talcum powder were detected by ICP-OES.Results indicated that the relationship between the responds and the mass concentration of the four elements shows good linearity within the range of 0.5-6,0.05-0.5,0.02-0.2 and 2-20 mg·L-1,respectively.All the correlation coefficients are higher than 0.999.Spiked recoveries of the four elements are between 88.0% and 108.8%.This method has been applied for quick screening of forbidden and restricted elements in cosmetics,with satisfactory results.
