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.
