ASTM D1888 Chemical Oxygen Demand in Hazardous Waste Liquids
The ASTM D1888 standard provides a method to determine the chemical oxygen demand (COD) of hazardous waste liquids. COD is an important parameter used to assess the biodegradable content of liquid waste streams, which helps in understanding the potential environmental impact and treatment requirements.
The COD test measures the amount of oxygen that can be consumed by all organic and inorganic reducible substances present within a water or wastewater sample. This process involves oxidizing these compounds with potassium dichromate in an acidic medium under controlled conditions, typically at 2小时候回复
