摘要
通过测定不同浓度的过氧化氢(H_(2)O_(2))所对应的化学需氧量(COD),建立了线性关系。采用加碱和加热(80℃水浴,带冷凝)的方法,消除了不同水样中H_(2)O_(2)对COD测定的影响,误差相对较小。
The linear relationship of chemical oxygen demand(COD)corresponding to different concentrations of hydrogen peroxide(H_(2)O_(2))was determined.By adding alkali and heating(80℃water bath,with condensation),the interference of H_(2)O_(2)on COD determination was eliminated in different wastewater,and the relative errors were acceptable.
