摘要

Water hyacinth (Eichhornia crassipes) is a highly invasive aquatic plant in Indonesia, where its rapid proliferation causes severe ecological degradation, blockage of waterways, and socio-economic disruption. Converting this problematic biomass into value-added functional materials represents a sustainable mitigation strategy. This study aimed to develop a nanocellulose-based bioaerogel derived from water hyacinth for the adsorption of volatile organic compounds (VOCs), with formaldehyde as a target pollutant. Nanocellulose was isolated through delignification and bleaching processes, followed by physicochemical and structural characterization. The bioaerogel was fabricated via freeze-drying and evaluated through formaldehyde adsorption experiments, non-linear isotherm and kinetic modeling, reusability tests, and external validation under VOC conditions simulating real applications. The results showed that the bioaerogel exhibited a high formaldehyde adsorption capacity, with a maximum Langmuir uptake of 62.32 ± 4.47 mg/g. The adsorption kinetics were best described by the pseudo-second-order model, indicating rapid and efficient adsorption behavior. The bioaerogel retained approximately 60% of its adsorption capacity after ten reuse cycles. Chamber tests demonstrated an 83.5% reduction in formaldehyde concentration within 360 min, while external validation using VOCs emitted from paint, plastic, and adhesive sources confirmed the reliability of the adsorption performance. Overall, nanocellulose-based bioaerogel derived from water hyacinth shows strong potential as an effective, regenerable, and environmentally friendly VOC adsorbent, while offering a promising pathway for the sustainable utilization of invasive aquatic biomass.
