COD in Landfill Seepage Water

Prove InstrumentsPhotometric determination of chromate consumption subsequent to digestion

Sample Preparation

Adaptation to the measuring range appropriate to the sample can be achieved by selecting the most suitable test. Higher concentrations of COD (> 90 000 mg/l) require dilution of the sample with COD-free water.

Analysis

Determine with the below mentioned test kits.

Calculation

COD content in mg/l COD = analysis value in mg/l COD
If the sample has been diluted with water, the result should be multiplied by the dilution factor.
