Comparison of Catalysts Used to Determine CODCr of Severe Domestic Sewage
摘要
Abstract
[Objective] The study aimed to find the best catalyst for the determination of CODCr of severe domestic sewage. [Method] Adopting potassium dichromate reflux method, respectively using MnSO4, Ag2SO4 · MgSO4, CuSO4, Kal ( SO4 )2, CuSO4 · KA1(SO4)2 · ( NH4)2MoO4 and Ag2SO4 · Al2(SO4)3 · MgSO4 as catalysts, we determined CODCr of severe domestic sewage, and compared their results with Ag2SO4. [Result] Used as catalysts in the determination of CODCr of severe domestic sewage,MnSO4, Ag2SO4 · MgSO4 ,CuSO4 ,Kal(SO4)2, CuSO4 · Kal(SO4)2 · (NH4)2MoO4 and Ag2SO4 · Al2(SO4)3 · MgSO4 had good catalytic effects, especially Ag2SO4 · Al2(SO4)3 · MgSO4. Average CODCr of Ag2SO4 · Al2 (SO4)3 · MgSO4 and Ag2SO4 was 229. 32 and 254. 28 mg/L separately, that is, the former accounted for 90. 18% of the latter, so the result of Ag2 SO4 could reflect the actual COD Cr of severe domestic sewage better. [Conclusion] Ag2SO4 is the optimal catalyst for the determination of CODCr of severe domestic sewage.关键词
