Recovery of p-hydroxybenzoic acid from wastewaters by reactive extraction 1. Extraction mechanism and influencing factors
Environmental Engineering and Management Journal › Vol. 7 › Nr. 2 AbstractThe comparative study on reactive extraction of p-hydroxybenzoic acid with Amberlite LA-2 and D2EHPA in two solvents with different polarity (n-heptane and dichloromethane) indicated that the extractant type and solvent polarity control the extraction mechanism. Thus, the reactive extraction with Amberlite LA-2 occurs by means of the interfacial formation of an aminic adduct with three extractant molecules in low-polar solvent, or of an salt with one extractant molecule in higher polar s...

Study of the separation process of tartaric acid by ion-exchange with solid anionites Amberlite IRA-67 AND Amberlite IRA-410
Environmental Engineering and Management Journal › Vol. 7 › Nr. 4 AbstractThe present work describes an investigation of process of ion-exchange separation of tartaric acid in model systems. These investigations will be used for the separation of tartaric acid from secondary wine products. Their valorisation allows obtaining valuable compounds, as well as decreasing the huge quantities of wastes accumulated at wine making factories.As ionic exchangers, there have been used weakly basic anion exchanger Amberlite IRA-67 (tertiary functional amine groups) and str...
