P. Guedes acknowledges Fundação para a Ciência e a Tecnologia for the Post-Doc fellowship SFRH/BPD/114660/2016.The electrochemical (EC) process for the removal of 2,4,6-trichloroanisole (TCA) from cork discs was investigated for the first time. For process development, six different EC reactors (based on a 3-compartment set-up) and four process variables were tested. Independently of the reactor design used, the application of a low level direct current for 8 h (10 mA, 0.16 mA/cm2) had a positive effect on TCA removal. The best option is to place the cork discs in a middle compartment separated from the cathode compartment by the use of a passive membrane, and from the anode compartment by a cation exchange membrane. In this reactor design, the TCA levels in 78% of the cork discs decreased to values below limit of detection (0.49 ng/L; TCA initial concentration between 0.5 and 2 ng/L). By immersing the discs’ in a saline solution for 24 h prior current application, the TCA removal was improved by 10–15%. When the 34 cork discs contaminated with 2.5 times-fold more TCA were subjected to EC after 24 h immersion in the saline solution, the percentage of discs in which TCA concentration was below 0.49 ng/L decreased to 41%. Still, and considering that TCA perception threshold in wines starts at 1.5 ng/L, 85% of the cork discs exposed to EC reatment presented TCA levels below the threshold. Results showed that the here developed EC system could be a viable method for the removal of TCA from cork discs.CENSE - Centro de Investigação em Ambiente e SustentabilidadeDCEA - Departamento de Ciências e Engenharia do AmbienteRUNGuedes, PaulaMateus, Eduardo P.Ribeiro, Alexandra B.Fernandes, José P.2023-04-02T00:31:38Z2019-04-012019-04-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article9application/pdfhttps://doi.org/10.1016/j.cej.2018.12.040eng1385-8947PURE: 11639830http://www.scopus.com/inward/record.url?scp=85058423313&partnerID=8YFLogxKhttps://doi.org/10.1016/j.cej.2018.12.040info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-05-22T17:41:13Zoai:run.unl.pt:10362/82335Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-05-22T17:41:13Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
