中文摘要：
该文研究了在碳纤维微电极上修饰锑一氧化锑，制备pH传感器的方法。通过对不同pH溶液进行电位测定，得出在4．6×10^-4mol／LSb^3＋的HCl（0．01mol／L）溶液中，先在-1．2V还原120s，再在2．0V氧化100s，得到的电极对pH有较好的响应，响应斜率-50～-60mV／pH，响应范围pH0．5～pH7．6，应用在实际样品的测定中取得较好的结果。
英文摘要：
In this paper, the carbon fibre microelectrode modified antimony - antimony oxide had been made to be the pH solid - state sensors. By the way of the potentiometric determination of different pH solutions, the best modified condition was researched： in the concentration of 4. 6×10 ^- 4 mol/L antimony in HCl solution （0.01 mol / L）, the electrode was first reduced at the potential of - 1.2 V for 120 s, then oxide at the potential of 2.0 V for 100 s. In this way, the modified electrode could have a good response to pH, and the response slope was - 50 - - 60 mV/pH while the pH response range was from 0. 5 to 7.6. Moreover, it could be applied in the determination of real samples.
