Water quality. Physical, chemical and biochemical methods -- Method for the determination of the chemical oxygen demand
This Section of BS 6068 describes a method for the determination of the chemical oxygen demand, COD, of water.
It is applicable to most kinds of waters having a COD value higher than 30 mg/L (see also the note in clause 9). The maximum COD value that can be determined on an undiluted sample is 700 mg/L. It is not applicable to highly saline waters containing (after dilution) more than 1 000 mg/L of chloride, such as sea and oilfield waters.
NOTE 1 For interferences, see clause 9.
NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.
