According with the last, this work is related to arsenic incorporation at room temperature in decomposed potassium jarosite. The work began with the synthesis of the compound at 75 \u00b0C for 9 h using Fe2(SO4)3 and K2SO4 at a pH of 1.1. Once jarosite was obtained, solids were subjected to an alkaline decomposition using NaOH at pH 10 for 30 min, and then As was added to the solution as HAsNaO4 and the pH modified by adding HNO3 until it reached a value of 1.1. The initial, intermediate, and final products were wholly characterized by scanning electron microscopy (SEM) in conjunction with energy dispersive spectrometry (EDS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy (RS), and X-ray photoelectron spectrometry (XPS). The obtained results show that As(V) can be adsorbed by ionic exchange in the amorphous FeOH structure of decomposed jarosite and when pH decreased to 1.1, the compound recrystallized, incorporating up to 6% As on average, which is indicative that this process can be used to reduce As in contaminated waters.<\/jats:p>","DOI":"10.3390\/ijerph192315912","type":"journal-article","created":{"date-parts":[[2022,11,30]],"date-time":"2022-11-30T02:21:57Z","timestamp":1669774917000},"page":"15912","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Synthesis, Characterization and Decomposition of Potassium Jarosite for Adsorptive As(V) Removal in Contaminated Water: Preliminary Study"],"prefix":"10.3390","volume":"19","author":[{"given":"Eduardo","family":"Cerecedo-S\u00e1enz","sequence":"first","affiliation":[{"name":"Academic Area of Earth Sciences and Materials, Institute of Basic Sciences and Engineering, Autonomous University of the State of Hidalgo, Highway Pachuca-Tulancingo km. 4.5, Mineral de la Reforma, Pachuca 42184, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"El\u00edas","family":"Hern\u00e1ndez-Lazcano","sequence":"additional","affiliation":[{"name":"Academic Area of Earth Sciences and Materials, Institute of Basic Sciences and Engineering, Autonomous University of the State of Hidalgo, Highway Pachuca-Tulancingo km. 4.5, Mineral de la Reforma, Pachuca 42184, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maythe J.","family":"Gonz\u00e1lez-Bedolla","sequence":"additional","affiliation":[{"name":"Academic Area of Earth Sciences and Materials, Institute of Basic Sciences and Engineering, Autonomous University of the State of Hidalgo, Highway Pachuca-Tulancingo km. 4.5, Mineral de la Reforma, Pachuca 42184, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0275-1196","authenticated-orcid":false,"given":"Juan","family":"Hern\u00e1ndez-\u00c1vila","sequence":"additional","affiliation":[{"name":"Academic Area of Earth Sciences and Materials, Institute of Basic Sciences and Engineering, Autonomous University of the State of Hidalgo, Highway Pachuca-Tulancingo km. 4.5, Mineral de la Reforma, Pachuca 42184, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0714-4421","authenticated-orcid":false,"given":"Ra\u00fal","family":"Rosales-Ib\u00e1\u00f1ez","sequence":"additional","affiliation":[{"name":"Tissue Engineering and Traslational Medicine Laboratory, Faculty of Higher Education, Iztacala, National Autonomous University of Mexico, Tenayuca-Chalmita S\/N, Cuautepec, Barrio Bajo, Alcald\u00eda Gustavo A.
