摘　　要：针对 COD快速测定法对于中小规模实验室批量测试成本高的问题 ,我们研究了一种使标准法与分光光度法相结合的 CODCr新测定方法。新的 COD测定方法比传统的测定法可减少重铬酸钾、硫酸汞用量 5 0 % ,硫酸用量减少 5 1 % ,不仅节省费用 。On the question of high cost of Lab-batch test of fast determining COD measure for middling and small cities.A new determining measure combining standard method with spectrophotometic titration was carried out.Comparing with traditional method,the new measure can reduce 50% of K 2Cr 2O 7 and HgSO 2 amount,51% of H 2SO 4 amount,not only save cost,but also reduce environment pollution of laboratory.
