| Popis: | Differential pulse polarography has been used to investigate the complexation reaction occuring between copper (II) ions and some naphthoquinonic derivatives. The importance of the substituent at the 2-position on the naphthoquinone ring has been demonstrated. Compared with 1,4-naphthoquinone which exhibits a very weak complex, the presence of a methyl group enhances the complexation reaction while a hydroxy group has an inhibiting effect. Naftazone, which includes a semicarbazone group, gives rise to a stronger reaction due to the participation of the side chain i n the complex formation. |
