Abstract:
Cathodic electrochemiluminescence (CECL) of hydroxychloroquine (HCQ) in aqueous solutions on an aluminum electrode is described. The analytical possibilities of the phenomenon are evaluated. The conditions for HCQ determination in slightly alkaline and acidic solutions are optimized. The possibility of analysis in the concentration range 0.1 - 300 mg/L is shown. CECL can be a supplement to well-known methods of HCQ determination in pharmaceuticals by a method based on a new type of luminescent response signal.
