Batch removal of Cu(II) from water by powdered seeds of Peganum Harmala has been investigated in this research. The Peganum Harmala seeds were collected after which they have been beaten slowly, separated and then cleaned using a sieve. The prepared sorption is characterized by FT-IR. Batch adsorption studies have been undertaken in 100 ml Erlenmeyer flasks, inside an incubator container. The main process parameters that are considered are pH, contact time, Cu(II) concentration, the Adsorbent dose effect and reaction temperature effect. Cu(II) is measured at a wavelength of 620 nm, using a UV-vis spectrophotometer. The result evidence that the maximum removal of Cu(II) is observed at pH 6.2, with the pH over 6.2 result to participate the copper hydroxide. Clearly, the uptake process of the Cu(II) ion occurres very swiftly from the outset of the experiments during the first 15 min, after which there is a low decrease until 40 min, when maximum adsorption of Cu(II) ion onto Peganum Harmala is observed. An increased Cu(II) ions removal percentage occurres with increasing dose of adsorbents, increasing from 0.2 to 0.6 g followed by an increased percentage removal from 63.50% to 66.02%. Subsequently, the removal of Cu(II) ions decline, with an increased dose to 1g. Langmuir adsorption isotherm is more appropriate than the Freundlich adsorption isotherm, while the pseudo second-order reaction model is suitable for adsorption of the Copper ion onto the active centers of the Peganum Harmala surface compared with the pseudo first-order model.

Peganum Harmala 植物作为吸附剂去除水中的铜 (II) 离子

在这项研究中，已经研究了用 Peganum Harmala 粉状种子从水中批量去除 Cu(II)。收集 Peganum Harmala 种子，然后将它们缓慢敲打、分离并用筛子清洗。制备的吸附用 FT-IR 表征。批量吸附研究已在 100 毫升锥形瓶中进行，位于培养箱容器内。考虑的主要工艺参数是p H、接触时间、Cu(II) 浓度、吸附剂剂量效应和反应温度效应。使用紫外-可见分光光度计在 620 nm 的波长下测量 Cu(II)。结果证明在p H 6.2 时观察到 Cu(II) 的最大去除，pH 超过 6.2 结果参与氢氧化铜。显然，从实验开始的前 15 分钟内，Cu(II) 离子的吸收过程发生得非常迅速，此后直到 40 分钟，Cu(II) 离子最大吸附到 Peganum Harmala被观察到。随着吸附剂剂量的增加，Cu(II) 离子去除百分比增加，从 0.2 增加到 0.6 g，然后去除百分比从 63.50% 增加到 66.02%。随后，Cu(II) 离子的去除量下降，剂量增加到 1g。Langmuir 吸附等温线比 Freundlich 吸附等温线更合适，而伪二级反应模型与伪一级模型相比更适合将铜离子吸附到 Peganum Harmala 表面的活性中心上。
