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.
