摘要
化学需氧量是水质监测的重要指标也是水质评价的重要依据,该指标反映水体受还原性物质污染的程度。与国标中测定化学需氧量的重铬酸钾法相比,紫外吸收法具有测定速度快、不会对环境造成污染等优点。本文对该方法的可行性进行试验研究,并探讨了温度对测定结果的影响。
Chemical oxygen demand was an important index of water quality monitoring and water evaluation.It reflected the degree of water pollution by reducing substances.Compared with the national standard method of dichromate method,it had many advantages,such as high measuring speed and no pollution to environment.The feasibility of the method,and the influence of temperature to the result were discussed.
