“…The versatility of amine resins allows their use in a wide range of pH and temperature conditions, maintaining their stability under most common processing conditions, and in the recovery of various compounds [30]. Among these resins, Dowex™ Marathon™ WBA and Dowex™ Marathon™ MSA are amine resins commonly used in water demineralization; technetium, uranium and iron recovery [21], [23], [24]; lactic acid recovery [6]; and ionic liquids purification [22]. The main differences between the resins are that the WBA is a weak base anion resin while the MSA is a strong base anion resin.…”

Un método de adsorción utilizando la resina Dowex™Marathon™ WBA ha sido desarrollado con el fin de evaluar larecuperación de ácido cítrico producido por fermentación sumergida. Para determinar la viabilidad de este método de separación, la resina fue evaluada a diferentes condiciones de temperatura (30 – 70 °C) y pH (1.5 – 6.5). Los resultadosmostraron que a pH bajo, se mejora la adsorción de ácido cítrico, a través de la cual, se recupera el 85% del ácido y se obtiene una pureza del 92%. Esto representa una capacidad máxima de adsorción de 0.46 g de ácido cítrico por gramo de resina empleada.
