Water quality - Determination of the chemical oxygen demand index (ST-COD) - Small-scale sealed-tube method

DS/ISO 15705-2006 发布历史

This standard specifies a method for the determination of chemical oxygen demand (ST-COD) using the sealed tube method. The test is empirical and is applicable to any aqueous sample, which includes all sewage and wastewaters. The method is applicable for undiluted samples having ST-COD values up to 1000 mg/l and a chloride concentration not exceeding 1 000 mg/l. Samples with higher ST-COD values require predilution. For samples with a low COD, the precision of the measurement will be reduced and the detection limit will be poorer. Samples with a high chloride concentraton will need to be prediluted to give a chloride concentration of approximately 1 000 mg/
