| Abstract: | The application of differential pulse polarography to brucine reaction product, having electroanalytical activity, with HNO_3 has been reported in this paper. The optimum conditions for the determination of brucine are found. By means of cyclicovoltammetry the electrochemical behavior of brucine on the electrode has been studied. This method has high sensitivity, and may be applied to determine the quantity of brucine in plant sample. |
