Abstract

The dithizone test is frequently used as a color test for lead in the confirmation of projectile wipes. An adjustment of test conditions will also allow the dithizone reaction to be conducted as a microcrystalline test, thereby increasing the specificity of the reaction. The color resulting from the formation of the inner salt complex between dithizone and the lead cation is maintained, and may be observed on the characteristic crystals obtained.
