摘要

本研究利用聚乙烯多胺改性甘蔗渣废弃生物质制备了一种新型绿色低成本生物吸附剂,用于去除水溶液中的钼(VI)。通过 SEM-EDS、BET、TG、傅立叶变换红外光谱、XPS 和批量吸附实验,研究了胺功能化甘蔗渣吸附剂(SCB-A)对钼(VI)的结构特性和吸附机理。结果表明,SCB-A 与 Mo(VI) 的吸附反应是一个自发的内热过程,其理论最大吸附容量约为 231.48 mg/g。其吸附容量是原始甘蔗渣的 8.93 倍。该吸附过程与 Langmuir 模型和假二阶动力学模型较为一致,表明该过程是在均匀表面上的单层吸附,吸附速率由化学吸附过程控制。SCB-A 具有很好的重复使用性,经过五次循环后仍能保持稳定的吸附容量。对于 Mo(VI) 的吸附,SCB-A 在多离子共存溶液中也表现出卓越的选择性。因此,SCB-A 在经济、可行地去除废水中的钼(VI)方面具有巨大的潜力。

Effective Removal of Molybdenum(VI) from Aqueous Solution Using Polyethylene Polyamine-Grafted Sugarcane Bagasse Biosorbent

A novel greenness and low-cost biosorbent was prepared by polyethylene polyamine-modified waste biomass of sugarcane bagasse in this study, which was used to remove molybdenum(VI) from aqueous solution. The structural properties and adsorption mechanism of this amine-functionalized sugarcane bagasse adsorbent (SCB-A) on Mo(VI) were investigated by SEM–EDS, BET, TG, FTIR, XPS, and batch adsorption experiments. The results show that the adsorption reaction between SCB-A and Mo(VI) was a spontaneous endothermic process, and its theoretical maximum adsorption capacity was about 231.48 mg/g. The adsorption capacity was 8.93-fold compared to that of pristine sugarcane bagasse. This adsorption process was more consistent with the Langmuir model and pseudo-second-order kinetics model, indicating that this process was monolayer adsorption on a homogeneous surface and the adsorption rate was controlled by the chemisorption process. SCB-A possessed great reusability, maintaining a stable adsorption capacity after five recycles. For the adsorption toward Mo(VI), SCB-A also exhibited superior selectivity in a multi-ion coexistence solution. Therefore, SCB-A has tremendous potential in the economically and feasible removal of Mo(VI) from wastewater.

期刊介绍: Journal of Sustainable Metallurgy is dedicated to presenting metallurgical processes and related research aimed at improving the sustainability of metal-producing industries, with a particular emphasis on materials recovery, reuse, and recycling. Its editorial scope encompasses new techniques, as well as optimization of existing processes, including utilization, treatment, and management of metallurgically generated residues. Articles on non-technical barriers and drivers that can affect sustainability will also be considered.
