In this work, a complex mixture of chlorobenzene and dichlorobenzenes in a non-ionic surfactant emulsion has been carried out by volatilization. Since this techhnique is strongly affected by the presence of the surfactant, modifying the vapour pressure, Pv0, and activity coefficient, \u03b3, a correlation between Pvj0\u03b3j and surfactant concentration and temperature was proposed for each compound, employing the Surface Response Methodology (RSM). Volatilization experiments were carried out at different temperatures and gas flow rates. A good agreement between experimental and predicted remaining SVCOCs during the air stripping process was obtained, validating the thermodynamic parameters obtained with RSM. Regarding the results of volatilization, at 60 \u00b0C 80% of SVCOCs were removed after 6 h, and the surfactant capacity was almost completely recovered so the solution can be recycled in soil flushing.<\/jats:p>","DOI":"10.3390\/ijerph19127547","type":"journal-article","created":{"date-parts":[[2022,6,21]],"date-time":"2022-06-21T01:43:27Z","timestamp":1655775807000},"page":"7547","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Non-Ionic Surfactant Recovery in Surfactant Enhancement Aquifer Remediation Effluent with Chlorobenzenes by Semivolatile Chlorinated Organic Compounds Volatilization"],"prefix":"10.3390","volume":"19","author":[{"given":"Patricia","family":"S\u00e1ez","sequence":"first","affiliation":[{"name":"Chemical Engineering and Materials Department, Complutense University of Madrid, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aurora","family":"Santos","sequence":"additional","affiliation":[{"name":"Chemical Engineering and Materials Department, Complutense University of Madrid, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9177-2481","authenticated-orcid":false,"given":"Ra\u00fal","family":"Garc\u00eda-Cervilla","sequence":"additional","affiliation":[{"name":"Chemical Engineering and Materials Department, Complutense University of Madrid, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arturo","family":"Romero","sequence":"additional","affiliation":[{"name":"Chemical Engineering and Materials Department, Complutense University of Madrid, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4235-9308","authenticated-orcid":false,"given":"David","family":"Lorenzo","sequence":"additional","affiliation":[{"name":"Chemical Engineering and Materials Department, Complutense University of Madrid, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,20]]},"reference":[{"key":"ref_1","unstructured":"Pay\u00e1 Perez, A., and Rodr\u00edguez Eugenio, N.
