摘要: 建立了电感耦合等离子体发射光谱法(ICP-OES)测定化妆品中8种重金属元素(Hg、Pb、Cr、Ni、Cd、As、Bi、Ti)含量的方法。化妆品样品采用微波消解法消解,消解液为8 mL硝酸+4 mL过氧化氢。结果显示,8种重金属元素在0.02~2.0 μg/mL线性范围内呈良好的线性关系,检测限为0.50~2.03 μg/L,相关系数为0.999 4~0.999 8,RSD均小于5%。Hg、Pb、Cr、Ni、Cd、As、Bi和Ti的平均加样回收率分别为95.83%,99.78%,95.81%,102.98%,96.89%,99.97%和96.65%,103.99%。20种化妆品中8种重金属的含量范围分别为Hg (0.03~0.75 mg/kg)、Pb (3.14~39.56 mg/kg)、Cr (2.45~15.57 mg/kg)、Ni (0~3.07 mg/kg)、Cd (0.58~4.20 mg/kg)、As (0.13~4.91 mg/kg)、Bi (15.69~30.86 mg/kg)、Ti (4.85~40.40 mg/kg)。本研究建立的ICP-OES法测定化妆品中8种重金属元素具有良好的精密度和准确性,可应用于化妆品中多种重金属元素的检测和化妆品质量控制。

Abstract:

An analytical method based on inductively coupled plasma optical emission spectrometry (ICP-OES) was established for the determination of eight heavy metal elements (Hg, Pb, Cr, Ni, Cd, As, Bi, and Ti) in cosmetics. Cosmetic samples were digested by the microwave digestion method, with the digestion solution consisting of 8 mL nitric acid and 4 mL hydrogen peroxide. The results show that the eight heavy metal elements exhibit a good linear relationship in the linear range of 0.02-2.0 μg/mL. The limits of detection are in the range of 0.50-2.03 μg/L, with the correlation coefficients in the range of 0.999 4-0.999 8, and the RSD less than 5%. The average spiked recoveries of Hg, Pb, Cr, Ni, Cd, As, Bi, and Ti are 95.83%, 99.78%, 95.81%, 102.98%, 96.89%, 99.97%, 96.65%, and 103.99%, respectively. In 20 cosmetic samples, the content ranges of the eight heavy metals are as follows: Hg (0.03-0.75 mg/kg), Pb (3.14-39.56 mg/kg), Cr (2.45-15.57 mg/kg), Ni (0-3.07 mg/kg), Cd (0.58-4.20 mg/kg), As (0.13-4.91 mg/kg), Bi (15.69-30.86 mg/kg), and Ti (4.85-40.40 mg/kg). The ICP-OES method established in this study for the determination of eight heavy metals in cosmetics has good precision and accuracy, and can be applied to the detection of multiple heavy metal elements in cosmetics as well as cosmetic quality control.
