摘要
本实验参照国家标准(GB11914-89)[1],对在相同时间、相同地点采集的水样在相同条件下进行手动滴定实验,所测结果与快速消解COD测定设备的结果进行数据对比,验证设备的准确性和重复性。
According to the national standard ( GB11914-89)[1],some water samples collected at the same time and same place were subjected to manual titration test under the same conditions. The measured results were compared with the results of the experimental device using COD fast digestion method to verify the accuracy and repeatability of this device.
