摘要

采用可可豆荚活性炭（CPAC）作为吸附剂，对水中的阿莫地喹进行了脱除。采用正磷酸（H3PO4）对原料可可豆荚（RCP）进行改性，提高其吸附性能。Langmuir等温线的qm值为321.33 mg -1，可以很好地描述吸附数据。伪二阶法（PSO）拟合效果较好，R2趋于1，SSE值较低，qe、cal和qe、exp值吻合度较高。热力学研究给出了负值ΔGo，正值ΔHo和大于80 kJ mol−1的Ea值，这证实了相互作用本质上是化学吸附。成本分析表明，CPAC比商用活性炭（CAC）便宜约8倍。CPAC是去除废水中AMO的可行且经济实惠的选择

Amodiaquine sequestration using cocoa pod based activated carbon

Cocoa pod-activated carbon (CPAC) was used as adsorbent for the removal of amodiaquine from aqueous solution in this study. Orthophosphoric acid (H₃PO₄) was used to modify the raw cocoa pod (RCP) to enhance its adsorptive properties. It was observed that the adsorption data was best described by the Langmuir isotherm having a q_m value of 321.33 mgg^-1. Pseudo Second Order (PSO) best fitted the adsorption data with R² tending towards 1, with a low SSE value and high agreement between q_{e, cal} and q_{e, exp} values. Thermodynamic study gave negative value of ΔG^o, positive value of ΔH^o and E_a value which is greater than 80 kJ mol⁻¹ , this confirms that the interaction is chemisorption in nature. Cost analysis shows that CPAC was about eight times cheaper than the commercial activated carbon (CAC). CPAC is a viable and affordable option for AMO removal from the wastewater

期刊介绍： Chemical Data Collections (CDC) provides a publication outlet for the increasing need to make research material and data easy to share and re-use. Publication of research data with CDC will allow scientists to: -Make their data easy to find and access -Benefit from the fast publication process -Contribute to proper data citation and attribution -Publish their intermediate and null/negative results -Receive recognition for the work that does not fit traditional article format. The research data will be published as ''data articles'' that support fast and easy submission and quick peer-review processes. Data articles introduced by CDC are short self-contained publications about research materials and data. They must provide the scientific context of the described work and contain the following elements: a title, list of authors (plus affiliations), abstract, keywords, graphical abstract, metadata table, main text and at least three references. The journal welcomes submissions focusing on (but not limited to) the following categories of research output: spectral data, syntheses, crystallographic data, computational simulations, molecular dynamics and models, physicochemical data, etc.
