Abstract:This research introduces an enhanced limonite‐based composite fiber adsorbent for arsenic (As) removal. The modification involves creating polyethersulfone (PES)–limonite composite fibers loaded with 60 wt% limonite powders, designed to be applicable in water flow environments. The fibers were prepared using a wet‐spinning process based on phase inversion, with varying concentrations (10, 20, and 30 wt%) of PES in NMP solution. The composite fiber with 10 wt% NMP exhibited a porous structure and demonstrated e… Show more
