Abstract

To establish a method for determination of lead in lipstick with microwave digestion and FAAS. Microwave digestion of samples with selected digestion conditions and FAAS were used to determine Pb in 10 lipstick samples. In the system of nitric acid (7.5 ml) and hydrogen peroxide (1.5ml), the time of microwave digestion was 10 minutes; a better result of digestion was obtained. The linear range and the detection limit of this method was 0.003 mg/l and 0.9994 respectively. The recovery rates of this method were 94.6%¿102.5%. This method is satisfied for determination of lead in lipstick samples.

微波消解-原子吸收光谱法测定口红中的铅

建立微波消解-原子吸收光谱法测定口红中铅的方法。采用微波消解法和原子吸收光谱法测定10种口红样品中的铅。在硝酸(7.5 ml)和双氧水(1.5ml)体系中，微波消解时间为10分钟;得到了较好的消化效果。方法的线性范围为0.003 mg/l，检出限为0.9994。该方法回收率为94.6% ~ 102.5%。该方法适用于口红样品中铅的测定。
