摘要
本文研究了十八烷基三甲基氯化铵(OTAC)改性蒙脱石对铯的吸附性能.探讨了时间、温度、用量、PH等对吸附效果的影响.结果表明:当吸附时间为60 min,吸附温度控制在50℃,吸附剂用量在0.9 g,PH为8时,OTAC改性蒙脱石对铯离子的吸附性能较好.OTAC改性蒙脱石吸附铯离子过程近似于准二级动力学且符合Langmuir等温吸附.
The adsorption properties of octadecyl trimethyl ammonium chloride（ OTAC） modified montmorillonite on cesium were studied in this paper. The effects of time,temperature,dosage and PH etc. on the adsorption effect were discussed. The optimum adsorption condition is confirmed as time,temperature,dosage and PH are60 min,40 ℃,0. 9 g and 8,respectively. The process of adsorbing cesium by OTAC modified montmorillonite is similar to that of pseudo second-order rate equation and accords with Langmuir isothermal adsorption.
