摘要1,4-苯醌作为高级氧化过程中产生的一种氧化中间体，因其高毒性而日益受到人们的关注。采用活性炭纤维（ACF）对1,4-苯醌进行了煅烧吸附去除。经过300℃煅烧后，ACF的表面形貌没有明显变化，但结果表明，热处理后的ACF的吸附去除效率比未处理的ACF提高了25.1%。能量色散x射线分析表明，热处理后ACF的氧含量明显增加，这可能是其吸附能力提高的原因。Langmuir等温线和拟二阶模型对实验数据拟合较好。在中性pH和25°C条件下吸附量最大，为315.2 mg/g。中性和酸性条件均有利于焙烧ACF对1,4-苯醌的吸附。离子强度效应实验……
AbstractAs an oxidation intermediate generated in advanced oxidation processes, 1,4-benzoquinone, a toxic intermediate has drawn increasing attentions due to its high toxicity. Activated carbon fibre (ACF) was calcined and employed for the efficient removal of 1,4-benzoquinone by adsorption. Although no noticeable change was observed on the surface morphologies of the ACF after calcination at 300°C, the results showed that the adsorptive removal efficiency of the thermally treated ACF was enhanced by 25.1% compared to the raw ACF. Energy dispersive X-ray analysis indicated that the oxygen content of the thermally treated ACF increased significantly, which might contributed to its higher adsorption capacity. Langmuir isotherm and pseudo-second-order model well fitted the experimental data. Maximal adsorption capacity of 315.2 mg/g was achieved at neutral pH and 25°C. Both neutral and acidic conditions were favorable for the 1,4-benzoquinone adsorption on the calcined ACF. The ionic strength effect experime...
