“…The extraction efficiency calculated in this work is in good agreement with the literature. 10,12 The stoichiometry of acid:extractant complex was estimated for chemical extraction of citric acid for all three extraction systems (A336, TBP, and TOA; diluted in MIBK). For TBP and A336, loading ratios (Z) were obtained to be low (Z<0.5), thus, only (1:1) acid:extractant complex formation was assumed.…”

“…Doubtlessly, active diluents provide a better solvation media to the carboxylic acid, and hence show greater efficiency. 5 Although studies on reactive extraction of various carboxylic acid are abundant in literature, the same for complete extraction study (equilibrium, kinetics and modeling) for citric acid are limited, a handful of research work can be found in the literature including equilibrium [5][6][7][8][9][10][11][12] and kinetic studies [12][13] of citric acid extraction. Bizek et al 9 were the first to study the physical and reactive extraction equilibria of citric acid in different diluent and trialkyamine as an extractant.…”

“…Poposka et al [27] studied the citric acid extraction from a solution containing 10% w/v of this acid. These authors used the extractant TOA (~43% w/w) in a mixture of isodecanol (~26% w/w) and a paraffinic diluent (~31% w/w).…”

“…However, studies on citric acid recovery by reactive liquid-liquid extraction with trioctylamine have shown that this stoichiometry can be changed in accordance with the composition of the organic phase and the temperature in which the reactions occur. 24 …”
