| Abstract: | The determination of COD in wastewater by potassium dichromate colorimetric method was discussed. Results showed the detection limit was 6mg/L, and errors were bigger under concentration of COD below 24mg/L.The practice process demonstrated this method was simple, fast, stable, cost effective, and monitoring apparatus was portable. |
