Electrochemical Investigation of Lignin Resin Doped with Different Ratios Rhodamine B
Keywords:Cyclic voltammetry, Lignin resin, Rhodamine B, supporting electrolyte.
The electrochemical behavior was investigated of Lignin Resin by using the cyclic voltammetry technique. Such investigation mainly focuses on the expected properties of the doped resin with different doping ratios of Rhodamine B (0.01, 0.5, 0.1, 0.15, 0.2) %wt. This is indicated by the electron transfer between the dopant and resin, which clearly shows the appearance of oxidation – reduction peaks accompanied log increase in electrical current Ip as applied potential changes. The heights of Ip oscillate due to the change in scan rate n. The results of linear of relationships between Ip with n1/2 indicated that the electron transfer was a process of one electron transfer.
