将稻壳在微波条件下制备成活性炭吸附剂,研究其对活性艳蓝KN-R的吸附特性。通过静态实验,考察了pH值、温度、时间、溶液起始浓度和吸附剂用量对吸附过程的影响。结果表明,当pH为2和12时吸附效果较好,最大吸附量分别为303.03、384.62 mg... 将稻壳在微波条件下制备成活性炭吸附剂,研究其对活性艳蓝KN-R的吸附特性。通过静态实验,考察了pH值、温度、时间、溶液起始浓度和吸附剂用量对吸附过程的影响。结果表明,当pH为2和12时吸附效果较好,最大吸附量分别为303.03、384.62 mg/g;随着温度的升高,达到吸附平衡的时间缩短;等温吸附过程可以用Langmuir方程来描述;动力学实验表明,吸附过程更符合拟二级动力学模型;热力学数据分析发现,吸附过程是自发进行的吸热过程。 展开更多

The wastewater discharged from tanneries lack biodegradability due to the presence of recalcitrant compounds at significant concentration. The focal theme of the present investigation was to use chemo-autotrophic activated carbon oxidation(CAACO) reactor, an immobilized cell reactor using chemoautotrophs for the treatment of tannery wastewater. The treatment scheme comprised of anaerobic treatment, sand filtration, and CAACO reactor, which remove COD, BOD, TOC, VFA and sulphides respectively by 86%, 95%, 81%, 71% and 100%. Rice bran mesoporous activated carbon prepared indigenously and was used for immobilization of chemoautotrophs. The degradation of xenobiotic compounds by CAACO was confirmed through HPLC and FT-IR techniques. 展开更多
