The removal efficiency of the pharmaceutical drug Mebeverine Hydrochloride (MEB) from solutions by an activated carbon (AC) prepared from dates stems was investigated in the present research work. The surface properties of the activated carbon were investigated by elementary analysis, BET surface area, SEM, FTIR and pH_pzc. The operating parameters effect on the MEB adsorption efficiency was investigated by using batch experiments. The adsorption isotherms study indicated that the experimental data were well described by Freundlich and DR isotherms, with the maximum adsorption capacity (q_max) of 4105 mg/g. This result suggests the multilayer adsorption of MEB on the activated carbon.

在本研究工作中，研究了由枣茎制备的活性炭 (AC) 从溶液中去除药物美贝维林 (MEB) 的效率。通过元素分析、BET 表面积、SEM、FTIR 和 pH _pzc研究了活性炭的表面性质。通过批量实验研究了操作参数对MEB吸附效率的影响。吸附等温线研究表明，Freundlich 和 DR 等温线很好地描述了实验数据，最大吸附容量 (q _max ) 为 4105 mg/g。该结果表明MEB在活性炭上的多层吸附。
