摘要

在这项工作中，我们报道了三丙胺季铵阳离子基单分散微球对废水中I−/IO3−的有效去除。得益于快速的溶剂交换过程和优异的三丙胺季铵阳离子离子选择性，这些微球在浓度为50 ppm时对I -和IO3 -的捕获率分别为98%和66%。同时，它们对I−和IO3−的吸附量分别为350 mg/g和370 mg/g，具有良好的可重复使用性。这些特点突出了它们在去除碘方面的优越实用性，特别是在放射性碘污染的水中。

Tripropylamine quaternary ammonium salt-based monodisperse microspheres for efficient and rapid removal of I−/IO3− from aqueous solutions

In this work, we report the efficient removal of I⁻/IO₃⁻ from wastewater by tripropylamine quaternary ammonium cation based monodisperse microspheres. Benefitting from the rapid solvent exchange process and the excellent ionic selectivity of tripropylamine quaternary ammonium cation, these microspheres show capture rate of 98% for I⁻ and 66% for IO₃⁻ at a concentration of 50 ppm. Meanwhile, they exhibit high adsorption capacities of 350 mg/g for I⁻ and 370 mg/g for IO₃⁻, coupling with excellent reusability. These characteristics highlight their superior practicability for removal of iodine, particularly in the context of radioactive iodine-contaminated water.
