| Abstract: | Objective To establish a method for detecting the inorganic ions in explosive residues. Methods The inorganic ion was separated in the capillary electrophoresis by using buffer and detected by UV indirectly.Results The inorganic anions (chloride, sulfate, nitrite, citrate, chlorate and perchlorate) and inorganic cations (ammonium, potassium, magnesium and sodium) in the explosive residues were separated successfully. Conclusion The method is of advantages, including high sensitivity, small sample quantity, and easy to operate. |
