Fabrication of recoverable plant polyphenol-based surfactants for efficient removal of uranyl ions from skin and cotton fabric
With the increasing demand for uranium in the nuclear industry, the unintended uranium contamination of skin or clothing for individuals involved in nuclear activities has raised public health concerns. Herein, a plant polyphenol-based surfactant (sulfonated bayberry tannin surfactant, SBTS) was fabricated by modifying the hydrophobic groups in the sulfonated bayberry tannin (SBT) structure using a simple Friedel–Crafts alkylation reaction. The surfactant modified with tetradecane chloride showed superior foaming ability and emulsifying properties compared with SBT. The characterization of SBTS by FT-IR spectroscopy confirmed that hydrophobic chains were successfully grafted on SBT molecules via covalent bonds. As expected, SBTS could disperse in water under near-neutral pH condition, and showed good foaming and emulsifying properties. Moreover, the surfactant exhibited effective removal ability for UO22+-contaminated cotton fabric and skin in a broad application range, reaching a removal rate of 99 % for low amounts of UO22+, and even above 55 % for high UO22+ amounts. More importantly, SBTS after reacing with UO22+ could be easily separated from aqueous systems after standing for 60 min in acidic and neutral conditions, which is a favorable feature to avoid secondary pollution. In vitro cytotoxicity tests suggested that SBTS was much safer than commonly used synthetic surfactants. Based on XPS and FT-IR measurements, we propose a decontamination mechanism mainly originating from the chelation effect between the phenolic hydroxyl group of SBTS and UO22+. This study highlights the potential of plant tannin surfactants as effective materials for the removal of UO22+ from skin or clothing of individuals involved in various nuclear-related activities.
期刊介绍:
Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
