Among the many variants for removing substance traces, which give an unpleasant smell to the air, membrane-based methods or techniques are viable options. Their advantages consist of installation simplicity and scaling possibility, selectivity; moreover, the flows of odorous substances are direct, automation is complete by accessible operating parameters (pH, temperature, ionic strength), and the operation costs are low. The paper presents the process of obtaining membranes from cellulosic derivatives containing silver nanoparticles, using accessible raw materials (namely motion picture films from abandoned archives). The technique used for membrane preparation was the immersion precipitation for phase inversion of cellulosic polymer solutions in methylene chloride: methanol, 2:1 volume. The membranes obtained were morphologically and structurally characterized by scanning electron microscopy (SEM) and high resolution SEM (HR SEM), energy dispersive X-ray analysis (EDAX), Fourier transform infrared spectrometry (FTIR), thermal analysis (TG, ATD). Then, the membrane performance process (extraction efficiency and species flux) was determined using hydrogen sulfide (H2S) and ethanethiol (C2H5SH) as target substances.<\/jats:p>","DOI":"10.3390\/membranes11040256","type":"journal-article","created":{"date-parts":[[2021,4,1]],"date-time":"2021-04-01T10:44:01Z","timestamp":1617273841000},"page":"256","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Removing of the Sulfur Compounds by Impregnated Polypropylene Fibers with Silver Nanoparticles-Cellulose Derivatives for Air Odor Correction"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8891-8948","authenticated-orcid":false,"given":"Aurelia Cristina","family":"Nechifor","sequence":"first","affiliation":[{"name":"Department of Analytical Chemistry and Environmental Engineering, University Politehnica of Bucharest, 1-7 Gheorghe Polizu St., 011061 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4304-0841","authenticated-orcid":false,"given":"Simona","family":"Cotorcea","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry and Environmental Engineering, University Politehnica of Bucharest, 1-7 Gheorghe Polizu St., 011061 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3793-6905","authenticated-orcid":false,"given":"Constantin","family":"Bung\u0103u","sequence":"additional","affiliation":[{"name":"Department of Engineering and Management, Faculty of Management and Technological Engineering, University of Oradea, 410087 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6082-830X","authenticated-orcid":false,"given":"Paul Constantin","family":"Albu","sequence":"additional","affiliation":[{"name":"Department of Radioisotopes and Radiation Metrology, IFIN Horia Hulubei, 30 Reactorului St., 023465 Magurele, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dumitru","family":"Pa\u0219cu","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry and Environmental Engineering, University Politehnica of Bucharest, 1-7 Gheorghe Polizu St., 011061 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8145-1094","authenticated-orcid":false,"given":"Ovidiu","family":"Oprea","sequence":"additional","affiliation":[{"name":"Department of Inorganic Chemistry, Physical Chemistry and Electrochemistry, University Politehnica of Bucharest, 1-7 Gheorghe Polizu St., 011061 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6271-6456","authenticated-orcid":false,"given":"Alexandra Raluca","family":"Grosu","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry and Environmental Engineering, University Politehnica of Bucharest, 1-7 Gheorghe Polizu St., 011061 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreia","family":"P\u00eer\u021bac","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry and Environmental Engineering, University Politehnica of Bucharest, 1-7 Gheorghe Polizu St., 011061 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7148-926X","authenticated-orcid":false,"given":"Gheorghe","family":"Nechifor","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry and Environmental Engineering, University Politehnica of Bucharest, 1-7 Gheorghe Polizu St., 011061 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,1]]},"reference":[{"key":"ref_1","first-page":"298","article-title":"Atmospheric pollution: A growing problem in public health","volume":"45","author":"Katz","year":"1955","journal-title":"AJPH"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"311","DOI":"10.1016\/0378-4274(79)90009-2","article-title":"The combined toxicity of ethanol and hydrogen sulfide","volume":"3","author":"Beck","year":"1979","journal-title":"Toxicol.
