摘要
分别利用荧光式和极谱式溶氧仪测量地表水中的溶解氧含量,比较两种溶解氧电极响应的线性、准确度、测量精密度和相对偏差,结果表明两种电极法测试溶解氧的数据无显著差异,测量结果和碘量法数据一致,荧光式溶氧仪的测量结果能满足测试要求。
The fluorescent dissolved oxygen analyzer and polarographic dissolved oxygen analyzer were used to measure the dissolved oxygen content in the surface water.By comparing the linearity of two dissolved oxygen elec⁃trodes,accuracy,RSD and relative deviation,it showed that there was no significant difference between two electrode methods for measuring dissolved oxygen.The measurement data of two electrode method were consistent with the io⁃dimetry data.The measurement results of fluorescent dissolved oxygen analyzer are satisfied with the demands of quality control.
