本文介绍了二氧化铱/铱(IrO_2/Ir)pH传感器的制备方法,探讨了传感器响应的可能机理,考查了该金属氧化物传感器对H~+的响应。实验发现在pH2.0～13.0范围内,该传感器对H~+呈良好的Nernst响应,斜率为56.33mV/pH,r=0.9985。将该传感器应用于酸碱滴定及污水中的pH测定,均获得满意的结果。
This paper introduces the preparation method of iridium oxide / iridium (IrO 2 / Ir) pH sensor, discusses the possible mechanism of the sensor response, and examines the metal oxide sensor response to H ~ +. It was found that the sensor showed a good Nernst response to H ~ + at pH 2.0 ~ 13.0 with a slope of 56.33mV / pH and r = 0.9985. The sensor used in acid-base titration and sewage pH determination, are satisfactory results.
