摘要
选取亚硝基二苯胺(NDPhA)作为目标污染物,采用高效液相色谱法,研究在不同反应条件下高铁酸钾(K_(2)FeO_(4))对NDPhA的去除效果,探讨其动力学规律。结果表明:随着反应的进行,NDPhA的去除率不断上升;K_(2)FeO_(4)投加量对去除效果的影响显著,随着投加量的增加,NDPhA的去除率不断升高;pH值影响NDPhA的去除率,当pH=6时,NDPhA的去除效果最好,去除率为64.47%;温度升高能促进NDPhA的去除,但促进作用不明显。K_(2)FeO_(4)降解NDPhA满足一级反应动力学规律。
In this study,nitrosodiphenylamine(NDPhA)was selected as the target pollutant,and the removal effect of it by potassium ferrate(K_(2)FeO_(4))under different conditions was studied by high performance liquid chromatography.The results indicated the dosageof.K_(2)FeO_(4) had a significant effect on the removal rate of NDPhA.With the dosage increased,the removal ratio enhanced.Moreover,the pH of the reaction condition affected the removal rate of NDPhA.When pH=6,the removal ratio achieved the best(64.47%).While,the effect of temperature was not obvious.The results clearly showed that the degradation process could fit the first-order kinetic model.
