摘　　要：本文报道了一种基于伏安法工作原理的新型溶解氧传感器。用其测定水中溶解氧与经典碘量法的结果比较,具有良好的一致法,误差<±6.3％。水中溶解氧10次重复测定结果的相对标准偏差为2%,该法灵敏度高,测定手续简便、快速、所需仪器简单,适用于环保部门水中溶解氧的日常检测,并可进一步用于生物传感器的研究。A new type of dissolved oxygen (DO) sensor by using voltammetry is introduced. The determination of DO in water by voltammetric DO sensor is in good agreement with that of calassical iodimetry, showing an error of 6.3% and the relative standard deviation is 2% for 10 times of determination. A novel method for the determination of DO in water by voltammetric DO sensor has been proposed. It is a simple, rapid, sensitive and repro- ductive one.
