Abstract
This study investigates the use of graphene oxide (GO) as a nanocollector to remove Zn ions from synthetic wastewater via ion flotation. The effect of various parameters, such as pH, GO concentration, air flow rate, impeller speed, and concentration of sodium dodecyl sulfate (SDS) as an auxiliary collector, on the removal of Zn ions was examined. Under optimal conditions (pH 8.5, GO concentration 40 mg/L, SDS concentration 37.5 mg/L, air flow rate 2 L/min, and impeller speed 800 rpm), Zn ion removal and water recovery reached 90% and 36%, respectively. Characterization techniques, including FTIR, SEM–EDX, and WDX, confirmed the successful interaction between GO and Zn ions, leading to the formation of Zn–GO complexes. This research highlights the potential of GO as a promising and efficient nanocollector for the removal of Zn ions from wastewater through ion flotation, contributing to environmental remediation efforts.
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.
