Scope
Main technical content: Applicable scope: This standard specifies the potentiometric titration method for determining the chemical oxygen demand (COD) in water. This standard is applicable to the determination of COD in surface water, domestic wastewater, and industrial wastewater. This standard is not applicable to the determination of COD in water with a concentration of chlorine compounds greater than 1000 mg/L (after dilution). When the sampling volume is 3.00 mL, the detection limit of this method is 1 mg/L, and the lower limit of determination is 4 mg/L. The upper limit of determination for undiluted water samples is 1000 mg/L. If the value exceeds this upper limit, the determination must be performed after dilution.
