Argentinian Sugar Cane Vinasse: Characterization of Phenolic Compounds and Evaluation of Adsorption as a Possible Remediation Technique

Chemical composition of sugar cane vinasse (Tucumán, Argentina) was studied finding high concentration organic compounds. Phenolic compounds were partially characterized, mostly flavonoids, anthocyanins, as well resorcinol and ferulic acid derivatives. Adsorption isotherms phenolic total measured on four commercial activated carbons with different physical chemical properties at two temperatures. The isotherm shape depends the type carbon adsorption capacity is enhanced temperature increases. Enthalpies process estimated, revealing that a chemisorption process, while physisorption three tested other one (CONCARBO).
