This dataset deals with the modification of granular activated carbon (GAC) with FeCl under basic conditions (pH ≈ 12) for removal of aluminium (Al) from aqueous solution. The structural properties and operational parameters including Al ion concentration (2.15 and 10.3 mg/L), pH solution (2-10), adsorbent dosage (0.1-5 g/L), and contact time (0-10 h) was investigated for raw and modified GAC. This dataset provides information about Al removal by GAC and modified GAC at conditions including: pH = 8, contact time = 6 h, initial Al concentration = 2.15 mg/L. The characterization data of the adsorbents was analysed by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and Brunauer, Emmett and Teller (BET) test. The data showed that Freundlich isotherm with and Pseudo second order kinetic model were the best models for describing the Al adsorption reactions. The acquired data indicated that the maximum adsorption capacity of GAC and modified GAC to uptake Al ( = 10.3 mg/L) was 3 and 4.37 mg/g respectively.
该数据集涉及在碱性条件（pH≈12）下用FeCl对颗粒活性炭（GAC）进行改性，以从水溶液中去除铝（Al）。研究了原始和改性GAC的结构性质和操作参数，包括Al离子浓度（2.15和10.3 mg/L）、溶液pH值（2 - 10）、吸附剂用量（0.1 - 5 g/L）和接触时间（0 - 10 h）。该数据集提供了在pH = 8、接触时间 = 6 h、初始Al浓度 = 2.15 mg/L等条件下，GAC和改性GAC去除Al的相关信息。通过傅里叶变换红外（FTIR）光谱、扫描电子显微镜（SEM）和布鲁诺尔-埃米特-泰勒（BET）测试对吸附剂的表征数据进行了分析。数据表明，Freundlich模型和伪二级动力学模型是描述Al吸附反应的最佳模型。所获得的数据表明，GAC和改性GAC对Al（ = 10.3 mg/L）的最大吸附容量分别为3和4.37 mg/g。
