Preparation of the carbon paste electrode Metal oxide modified carbon paste was prepared by mixing weighted amounts of the corresponding metal oxide and 300 mg of spectroscopic graphite powder. Then 120 mg of pharmaceutical paraffin was added and mixed thoroughly in a mortar until a homogeneous paste was obtained. The modified paste was packed in the end of a glass tube (about 1 mm I. D.) provided with a copper wire contact. The modified electrode was polished on a very fine smooth paper. 非常感谢！！！ |
