摘    要:流动时库仑分析法克服了电容电流及电极表面性质改变等噪声干扰。10 s内完成一次测定点。在“海水中溶解氧测定仪”的基础上,改为通用型仪器,使之微机化,进行数理统计处理,仪器的可靠性、再现性及灵敏度得到进一步提高,可测0.01 mg/l浓度,相应偏差±0.5~1.0%,进行了水中 Cr~(6+)、Cu~(2+)、O_2、Br~- 等测定,获得良好效果。

关 键 词:库仑分析仪  微机  库仑分析法

Abstract:Chronocoulometry for flowing soultion overcomes noise disturbance resulting from capacity current and variety of property of electrode surface.completing one determination within 10 seconds, having the advantage of rapidity, sensitivity, accuracy and good repeatability. So for such instrument had not been seen commercially. On the basis of dissolved oxygen analyzer. We develop into versatile instrument and have it microcomputer based. Carrying out mathematic and physic statistics disposition,reality,repeatability and sensitivity of instrument acquire further enhancement. The analyzer may detect concentration of 0.01 mg/1, corresponding deviation is?0.5- 1.0% .applying to determination of Crs+Cu2f,O2 and Br- in water, acquiring good effect.
Keywords:Microcomputer  Chronocoulometry  Cr6+  Cu2+  02  Br-
