The dithizone method has been used for the determination of trace amounts of lead in raw materials and products for cosmetics. However, in order to determine lead in a safer manner, we studied the application of atomic absorption method such as direct, correction with D2-lamp, and extraction to the routine work. As a result, it was found that this method can be effective for many kinds of these samples.
