설명

애플리케이션

Ammonium citrate dibasic can be used as both carbon and nitrogen precursor to synthesize nitrogen-doped fluorescent carbon nanoparticles (CNPs) for the development of sensitive and selective sensors for picric acid detection. Solution form of ammonium citrate can also be used in leaching experiments to extract copper nanoparticles from waste printed circuit boards (WPCBs).
