Synthesis of a novel diaquabis(1,10-phenanthroline)copper(II)chloride complex and its voltammetric application for detection of amoxicillin in pharmaceutical and biological samples

A novel electrochemical sensor based on a Cu-coordinated molecularly imprinted polymer and MoS2 modified chitin-derived carbon for selective detection of dextromethorphan

“…Cu-Phen) was prepared according to the reported method. 30 In brief, Phen (0.108 g) and CuCl 2 ·2H 2 O (0.051 g) were dissolved in methanol (15 mL), and stirred at room temperature overnight. After evaporating the solvent, a blue-green crystalline complex was obtained.…”

“…These changes were attributed to the complexation reaction between Cu 2+ and Phen. 30 Aer adding DXM to the Cu-Phen complex, the absorption peak at 227 nm shied to 222 nm, indicating the formation of the DXM-Cu-Phen ternary complex to some extent (Fig. 2B).…”
