Square wave voltammetric analysis of polyphenol content and antioxidant capacity of red wines using glassy carbon and disposable carbon nanotubes modified screen-printed electrodes
The polyphenols present in different French red wines were characterized electrochemically using square wave voltammetry (SWV). The voltammetric measurements were carried out using a glassy carbon electrode and disposable screen-printed carbon electrodes unmodified and modified with single- and multi-walled carbon nanotubes. The single-walled carbon nanotubes-modified screen-printed carbon electrode (SWCNTs-SPCE) showed the best results for the voltammetric analysis of polyphenols in ... إقراء المزيد
