Özet
The objective of this study is to investigate the removal efficiency of tartaric acid from aqueous solution and wine waste by gel and macroporous ion-exchange resins. The resin amount and pH have an important effect on the removal rate. The maximum removal of tartaric acid was achieved at pH ≥ 4. Tartaric acid adsorption isotherms were analyzed using Langmuir and Freundlich models. The results obtained have shown that Langmuir model fits well for both resins. Sorption kinetics for these resins fit to Ho pseudo-second-order kinetics model. The hybrid precipitation-cation exchange resin system was used for recovery of tartaric acid from liquid wine wastes. The obtained results showed that hybrid system can be used as an alternative method for the recovery of tartaric acid. The 90% of tartaric acid was recovered by hybrid system.
