摘要
化学需氧量(CODcr)作为废水性质的一个重要指标被广泛地应用,会受到无机物质双氧水的干扰。通过实验研究双氧水对CODcr测定的干扰程度,试图探索一种去除的最佳方案。针对水样中的双氧水干扰,探讨温度、双氧水初始浓度、pH值、金属离子、紫外光照等在固定时间里对双氧水分解效果,认为100℃水浴加热和调节水样pH为11是较优的两种去除双氧水方法。
Chemical Oxygen Demand, widely used as an indicator to identify the characters of wastewater, could be disturbed by hydrogen peroxide. This work has been carried out to study the interference of hydrogen peroxide in Chemical Oxygen Demand determinations under different conditions. The effects of temperature, initial concentration,PH, metal ion nd ultravioletlight irradiation, on the decompose of hydrogen peroxide were investigated. Results show that both heating and adjusting PH of the sample are effective methods.
