摘要
对重铬酸钾比色法测定水中化学需氧量(COD)的方法进行了验证性研究。结果显示,该方法检出限为6mg/L,化学需氧量浓度低于24mg/L时,测定误差比较大。运用过程表明,该方法具有简单、稳定、快速、成本低廉、监测仪器便于携带等优点。
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.
