摘要：One of the most common processes in forensic analysis is the identification of gunshot residues.Currently, there are super advanced methods for this procedure, however, it is known that many localities do not have the financial conditions to acquire these equipment.The suspect screening test is usually carried out by Griess, and sodium rodizonate assays, however, the latter has some drawbacks such as low stability, median cost, interaction with the Griess test, and preparation dependent on other reagents.The present study has developed a new method for identifying lead, with lower cost, greater stability and ease of preparation and that allows the nitrite test later.
