Resumo: Initially, we performed the synthesis and characterization of sec-butylammonium acetate IL and chitosan activation with it. Afterwards, we used the activated chitosan to carry out the adsorption of chromium VI, which is the main metallic ion present in tannery effluents. The influence of the adsorbent storage time, adsorbent amount, test time, pH and temperature were analyzed. The storage time indicated low influence on the treatment and on the quality of the adsorbent; however, drying after the impregnation process gave the material greater adsorption capacity. The adsorption time was 1 hour, the ideal amount of 1.00 g and the temperature 25 ° C. Regarding pH, no significant changes were observed in the amount adsorbed between 2 and 4.5. These previously determined conditions were used for the treatment of the tannery effluent, verifying the efficiency of chromium VI concentration reduction.

Posteriormente, foram realizadas as adsorções de cromo VI, principal íon metálico presente em efluentes de curtume, utilizando-se a quitosana ativada, sendo determinados a influência do tempo de estocagem do adsorvente, da quantidade de adsorvente utilizado, do tempo de ensaio, do pH e da temperatura ideais. O tempo de estocagem indicou baixa influência no tratamento e na qualidade do adsorvente, porém, a secagem após o processo de impregnação conferiu ao material maior capacidade de adsorção. O tempo de adsorção foi de 1 hora, a quantidade ideal de 1,00 g e a temperatura de 25ºC. Com relação ao pH, não foram verificadas alterações significantes na quantidade adsorvida entre 2 a 4,5. Essas condições previamente determinadas foram utilizadas para a realização do tratamento do efluente de curtume, sendo verificada a eficiência da redução do teor do mesmo.Universidade Federal de Viçosa - UFV2017-03-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/244694160302201726710.18540/jcecvl3iss2pp267-280The Journal of Engineering and Exact Sciences; Vol. 3 No. 2 (2017); 267-280The Journal of Engineering and Exact Sciences; Vol. 3 Núm. 2 (2017); 267-280The Journal of Engineering and Exact Sciences; v. 3 n. 2 (2017); 267-2802527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/2446941603022017267/pdfMorandim-Giannetti, Andreia AraújoEliodorio, Kevy PontesAndolfatto, Vitor SeorraMartins, Marco Rulevasde Sá, Breno PivaroUmeki, Erickinfo:eu-repo/semantics/openAccess2020-07-14T22:33:31Zoai:ojs.periodicos.ufv.br:article/2319Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2020-07-14T22:33:31The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
