摘要
该文采用羟基铝(离子)作柱化剂制备无机柱撑蒙脱石,探讨在不同投药量、吸附时间和pH值条件下,无机柱撑蒙脱石和纯蒙脱石对Cu2+的吸附效果,找出了吸附的适宜条件。结果表明,在相同条件下,无机柱撑蒙脱石对Cu2+的吸附效果优于纯蒙脱石,且两者的吸附等温线属于Langmuir型。
Hydroxyl-Al (Keggin cation) ions were used as the pillared interlayered agent to prepare inorganic pillared interlayered montmorillonite (IPIM) , and the adsorption effectiveness of Cu^(2+)on purified montmorillonite and IPIM was investigated respectively under varying experimental conditions including the dosage of the mineral, the adsorption time and the pH value. The results indicate that the adsorptive efficiency of IPIM is better than that of purified montmorillonite, and both of the adsorption curves conform to the Langmuir equation. The optimum conditions for adsorption were also found.
