Scope

Scope: This standard specifies the spectrophotometric determination method of chemical oxygen demand (COD) in water quality using pre-prepared reagents. This standard is applicable to the determination of COD in surface water, groundwater, domestic wastewater, and industrial wastewater. This standard is not applicable to saline water with a chloride ion concentration greater than 1,500mg/L after dilution. When the sampling volume is 2.00ml, the detection limit of the method specified in this standard is 4mg/L, the determination limit is 16mg/L, and the determination upper limit for undiluted water samples is 1,600mg/L.
