| Abstract: | A modification of the routine method for the determination of CODc_r in water is reported in this paper. A thorough study on the relation between the time of digestion and the acidity is made, and the optimum condition is established. The interference of chloride ion is eliminated through its precipitation as AgCl by silver nitrate instead of by mercuric sulfate. |
