摘要
文中探讨了全自动电位滴定仪分别测定高低浓度废水化学需氧量的分析结果,并与手动滴定进行比较,在浓度小于50 mg/L时,电位滴定相比手动滴定准确度更高,在保证较高的准确度和精密度的条件下,极大的缩短了分析时间。
In this paper,the analytical results of chemical oxygen demand in high and low concentration waste water by using automatic potentiometric titration are discussed. Under the condition of higher accuracy and precision,the analysis time is greatly shortened
