| Investigation Of Removal Of Various Carboxyllic Acids By Hydrogels From Solutions
Carboxyllic acids are biotechnological substances that used in many industries extensively. Therefore production and separation of carboxylic acids from product mixtures are important scientific and economical problems. In this work, it has been investigated that removal of acetic, citric, lactic and tartaric acids which used intensively from aqueous solutions. There are many works for separation of carboxyllic acids by using different processes and chemical substances in literature. As for in this work, hydrogels were used for removal of carboxylic acids from aqueous solutions. Hydrogels are important polymer substances which have been started to use in different technologies in recent years. In experimental works, firstly the effects of time, temperature and mixing on separation of carboxylic acids from aqueous solutions were investigated.
After experimental conditions have been determined, firstly, separation was taken place for different acid gel ratios at constant initial acid concentrations and determined equilibrium conditions. At last stage, it has been determined that the effect of different initial acid concentration on removal at constant hydrogel amount. Results obtained from experimental works have been used in Langmuir and Freundlich isotherms.
