Six ceramic nanocomposite membranes were fabricated by varying HNT content (75, 80, and 85 wt.%) and sintering temperature (900 and 1,000 \u00b0C), with constant grog (8 wt.%) and Mn3O4 additions. Water flux measurements demonstrated that membrane H85\u2013900 (85% HNTs, 900 \u00b0C) achieved the highest permeability of 390 L\/m2.h at 5 bar. Lead removal efficiency in synthetic aqueous solutions reached 99.84% for membrane H80\u20131,000 (80% HNTs, 1,000 \u00b0C). When tested with spiked real groundwater samples, the membranes maintained high performance, achieving 99.16% lead removal with the H80\u20131,000 membrane. The Mn3O4 nanoparticles used in this study were synthesized via co-precipitation and characterized based on particle size, crystal structure, and purity. Scanning electron microscopy (SEM) images revealed uniform crystalline particles with sizes of 30\u201340 nm. X-ray fluorescence confirmed 95.2% Mn3O4 purity, and X-ray diffraction indicated a tetragonal crystal structure. UV-visible spectra exhibited characteristic absorption peaks at 220 nm (O2\u2212\u2013 Mn2+\/Mn3+ charge transfer) and 350 nm (d-d crystal field transition). These results demonstrate the potential of locally sourced HNT-based ceramic membranes for effective heavy metal remediation in water treatment applications.<\/jats:p>","DOI":"10.2166\/wst.2026.265","type":"journal-article","created":{"date-parts":[[2026,5,14]],"date-time":"2026-05-14T12:44:22Z","timestamp":1778762662000},"page":"1278-1295","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":0,"title":["The effectiveness of nano-halloysite ceramic membranes in removing lead from polluted water"],"prefix":"10.2166","volume":"93","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-1231-2340","authenticated-orcid":false,"given":"Mariam","family":"Abu Ghadeer","sequence":"first","affiliation":[{"name":"1 Institute of Nanotechnology, Jordan University of Science and Technology, Irbid 22110, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7279-3324","authenticated-orcid":false,"given":"Ayat","family":"Bozeya","sequence":"additional","affiliation":[{"name":"1 Institute of Nanotechnology, Jordan University of Science and Technology, Irbid 22110, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9760-7594","authenticated-orcid":false,"given":"Borhan","family":"Albiss","sequence":"additional","affiliation":[{"name":"1 Institute of Nanotechnology, Jordan University of Science and Technology, Irbid 22110, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"945","published-online":{"date-parts":[[2026,4,24]]},"reference":[{"key":"2026060908122953900_WST-D-25-00668C1","doi-asserted-by":"crossref","first-page":"115170","DOI":"10.1016\/j.desal.2021.115170","article-title":"Current advances in membrane technologies for saline wastewater treatment: a comprehensive review","volume":"517","year":"2021","journal-title":"Desalination"},{"issue":"5","key":"2026060908122953900_WST-D-25-00668C2","doi-asserted-by":"crossref","first-page":"1253","DOI":"10.2166\/wpt.2022.039","article-title":"Heavy metals contamination in water, sediments and fish of freshwater ecosystems in Pakistan","volume":"17","year":"2022","journal-title":"Water Pract.
