Abstract

In this research paper, the amount of lactic acid recovery with adsorption process by strongly-anionic resins at 25, 30, 35, 40, 45 and 50°C were studied and also the effect of parameters in adsorption were investigated.Usual artificial ion exchange resin, are made on matrix non soluble long polymer, usually poly styrene, but some of these resins are based on Methacrilic Acid. Generally, IRA- 400, PVP-24, IRA-420, IRA-92 and Dowex- 50w are some of the important anion-basic resins and all of them were experienced in this research work. It is determined that IRI-400 has good performance and compatibility.Amberlite IRA-92 is an appropriate selection for lactic acid recovery as a weak basic resin. On the other hand, Amberlite IRA-400 is suitable one among strongly-basic resins. In the present work, the lactic acid adsorption isotherm in different temperatures was analyzed, and the best situation for lactic acid adsorption was observed in 45°C. Also, the best volumetric flow rate for resin washing with distilled water and normal sulfuric acid was 0.25 ml/min, totally. In addition, the effect of volumetric flow rate on the yield of acid recovery in DIL (=12/50) chromatographic column was studied. It was determined that removal of lactic acid in elution by distilled water is a quick process with lactic acid removal from solid surfaces approximately 60%. Then, elution of remained lactic acid (~40%) by sulfuric acid could be obtained with higher volume than utilized distilled water. The elution process was done by different volume flow rates. The results showed that using high flow rate of washing fluid could University College of Engineering, University of Tehran 5 affect the amount of required washing fluid and it was determined that optimum condition would be at the minimum flow rate of the washing fluid. For the situations similar to this experimental work, using 0.25 ml/min could be recommended. Generally, in the above optimum conditions, the efficiency of the recovery was 96% and the amount of productivity was 1.1 gr lactic acid in 1.0 gr resin.
