Electrochemical Investigation of Lignin Resin Doped withDifferent Ratios Rhodamine B

The electrochemical behavior was investigated of Lignin Resin by using thecyclic voltammetry technique. Such investigation mainly focuses on theexpected properties of the doped resin with different doping ratios ofRhodamine B (0.01, 0.5, 0.1, 0.15, 0.2) %wt. This is indicated by the electrontransfer between the dopant and resin, which clearly shows the appearance ofoxidation – reduction peaks accompanied log increase in electrical current Ipas applied potential changes. The heights of Ip oscillate due to the change inscan rate v. The results of linear of relationships between Ip with v1/2indicated that the electron transfer was a process of one electron transfer.
