【摘要】 用循环伏安法、计时库仑法研究了Ｂｒ－在不同电极上，以及不同浓度与不同ｐＨ值时的电氧化性质．测定了Ｂｒ－在１ｍｏｌ／ＬＨ２ＳＯ４介质中的扩散系数Ｄ和标准电极反应速度常数ｋ°．实验结果表明Ｂｒ－在Ｐｔ上的反应速度常数要比石墨电极上大一个数量级．根据不同实验条件的循环伏安图，提出了Ｂｒ－电氧化的可能机理．更多还原

【Abstract】 The characteristrics of the electrooxidation of bromide have been investigated at different electrodes,concentrations and pHs-value,using cyclic voltammetry and chronocoulometry. The diffusion coefficient (D) and the standard electrode reaction rate constant (k°) were measured. The experimental results indicate that the k°of bromide at platinum electrode is larger than that of at graphite electrode about 10 times. The possible mechanism of bromide electrooxidation was suggested according to the cyclic voltammgram.更多还原
