Replacing dichromate with hydrogen peroxide in the chemical oxygen demand (COD) test
Water Science and Technology, 2012 The widely used standard method for chemical oxygen demand (COD) involves hazardous chromium species, and its two-hour heating protocol entails a substantial amount of energy expenditure. In the present work we report a proof of concept for a major modification of this method in the range 10–800 mgCOD/L, whereby H2O2 is proposed as a replacement ...

Removal of Chemical Oxygen Demand (COD) from Swine Farm Wastewater by <i>Corynebacterium xerosis</i> H1. [PDF]
MicroorganismsSwine wastewater (SW) has a high chemical oxygen demand (COD) content and is difficult to degrade; an effective strategy to address this issue is through biodegradation, which poses negligible secondary pollution risks and ensures cost-efficiency. The objectives of this study were to isolate an effective COD-degrading strain of SW, characterize (at the
