摘要
为了研究了在不同温度条件下油页岩灰渣对亚甲基蓝的吸附性能,实验在装有亚甲基蓝水样的中,加入油页岩灰渣吸附剂,于不同温度下在振荡培养箱中,调节转数,振摇吸附。采用比色法测定吸附后亚甲基蓝的质量分数,根据其质量分数随吸附时间的变化,分析油页岩灰渣对亚甲基蓝的吸附性能。结果表明:油页岩灰渣对亚甲基蓝具有较强的的吸附能力,吸附反应发生较快,化学吸附占主要地位,并且符合二级反应动力学方程。
In order to study the adsorption properties of oil shale ash to methylene blue in wastewater under different temperature,methylene blue water sample is added to oil shale ash adsorbent under different temperature in oscillation incubator,regulating revolution and adsorbent.The mass fraction of methylene blue is determinates through colorimetry.According the change of mass fraction of methylene blue,adsorption properties of oil shale ash to methylene blue is analyzed.The results show that this process had the advantage of fast adsorption,good adsorption effect.Oil shale ash adsorbed Methylene Blue mainly via chemical adsorption and the adsorption process accorded with second-order reaction kinetics.
