摘要
五日生化需氧量是水质监测中的重要指标.对试样中溶解氧的测定方法进行比对分析,并对五日生化需氧量随温度的影响进行了详细研究.结果显示,在其他条件一定的情况下,电化学探头法在实验室测定五日生化需氧量中具有相对优势,且最佳测定温度为 20℃.在最优实验条件下,对实际样品的检出限、精密度和准确度进行了分析测定,结果均满足质控要求.
Abstract
Five day biochemical oxygen demand is an important indicator in water quality monitoring.Comparative analysis was conducted on the determination methods of dissolved oxygen in the sample,and a detailed study was conducted on the influence of temperature on the five day biochemical oxygen demand.The results showed that under certain other conditions,the electrochemical probe method has a relative advantage in determining the five-day biochemical oxygen demand in the laboratory,and the optimal measurement temperature is 20℃.Under the optimal experimental conditions,the detection limit,precision,and accuracy of the actual sample were analyzed and determined,and the results all met the quality control requirements.
