Mercaptosilane coupling agent surface modification of Fe-La nanoparticle to enhance its dispersion in PAN nanofibers for effective removing As (III): Dynamic membrane filters, trace As(III) and mechanism

Key Points

• Enhanced dispersion of Fe-La nanoparticles improves adsorption of As(III) in PAN nanofibers, leading to effective removal.
• In dynamic membrane filters, optimized particle surface modification significantly increases the filtration efficiency for arsenic.
• The method of mercaptosilane coupling agent treatment enhances the nanoparticles' interaction with the polymer matrix, improving performance.
• This approach may enable more efficient removal of toxic elements from water sources in real-world applications.
