Adsorption of Copper ( II ) , Cobalt ( II ) , and Iron ( III) Ions From Aqueous Solutions on Poly ( Ethyleneterephthalate ) Fibers. Journal of Applied Polymer Science, 68(12), 1935-1938.0021-8995https://hdl.handle.net/20.500.12395/16746The adsorption behavior of poly ( ethylene terephthalate ) ( PET ) fibers to-wards copper ( II ) , cobalt ( II ) , and iron ( III ) ions in aqueous solutions was studied by abatch equilibriation technique. Influence of treatment time, temperature, pH of thesolution, and metal ion concentration on the adsorption were investigated. Adsorptionvalues for metal ion intake followed the following order: Co ( II )úCu(II)úFe( III ) .One hour of adsorption time was found sufficient to reach adsorption equilibrium forall the ions. The rate of adsorption was found to decrease with the increase in thetemperature. Langmuir adsorption isoterm curves were found to be significant for allthe ions studied. The heat of adsorption values were calculated as05,02.8, and03.6kcal /mol for Cu ( II ) , Co ( II ) , and Fe( III ) ions, respectively.eninfo:eu-repo/semantics/closedAccessadsorptionfibrous adsorbantpoly(ethylene terephthalate) fibersmetal ionsindustrial waste treatmentArticle681219351939Q2WOS:000073313100006Q2
