“…The more solute is stripped, the more freed carrier molecules will be regenerated and diffused back to the external interface to facilitate extraction. A similar trend of extraction performance was also observed by Ng et al [23] and Othman et al [24]. However, with a further increase in the Na 2 CO 3 concentration up to 0.05 and 0.1 M, the extraction was reduced to about 56 and 49% respectively.…”

Succinic acid extraction and recovery from aqueous solution via emulsion liquid membrane (ELM) was investigated. The liquid membrane formulation consists of Amberlite LA2 as a carrier, palm oil as a diluent, sorbitan monooleate (Span 80) and polyoxyethylene sorbitan monooleate (Tween 80) as surfactants, sodium carbonate (Na2CO3) as a stripping agent, and octanol as a modifier. At the best condition of 0.01 M Na2CO3, 1:3 treat ratio, 0.7 M Amberlite LA2, 10% w/v modifier, and external solution of pH 2, the extraction of succinic acid was up to 71%. The optimization of recovery by response surface methodology (RSM) shows that around 40% of succinic acid was recovered. At the favorable condition, 84% of succinic acid was recovered with almost 100% purity. Hence, the ELM study can be extended to extract and recover succinic acid from real fermentation broth. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13065, 2019

“…The high cost of these POSs, toxicity, poor process safety, non-renewability, non-biodegradability, environmental pollution problems during solvent regeneration, ammability, depletion of world petroleum reserves, undesirable in uence on the activities of biochemical substances (such as microbes), and the pertinent progress of environmentally benign technologies have been considered in the dynamic research on environmentally benign green solvents for the separation and puri cation of LA from the aqueous solution [7,19]. In these years, a large reduction in the use of organic diluents from the industrial processes and their substitution by the environmentally benign green solvents (vegetable oils) have been intensively investigated [20]. The use of such a type of green solvents during the formulation of organic phase helps make industrial processes more environmentally benign and decrease the amounts of hazardous wastes [21].…”

“…during the organic phase formulation has been continuously grasping the attention of researchers and scientists across the world as a better alternative to these POSs [21]. These green solvents enjoy several pertinent physiochemical characteristics such as renewability, being economical, eco-friendliness, non-volatility, biodegradability, being nonpolluting, being easy to recoverable, and viscous nature (kinematic viscosity = 30-40 cSt at 38 C [20]) [22,23].…”

An environment-friendly reactive extraction method as a novel phase separation technique is considered to extract Lactic Acid (LA) from the aqueous solution by means of environmentally benign green diluents along with a synergistic mixture of extractants. Reactive extraction of LA was carried out through a synergistic mixture of extractants (trioctylamine (TOA), Aliquat336, and tridodecylamine (TDDA)), organic solvents, and non-toxic and biocompatible green diluents. According to the various investigated LA reactive extraction processes, the process featuring sun ower oil, synergist extractant (TOA and Aliquat336), and Butan-2-ol was found to be the most favorable system. The LA distribution coe cient (K D = 27:75 0:22) and extraction e ciency ( = 97:17 0:54%) were obtained by a system consisting of LA concentration (0.05 [M]), TOA (15%, v/v), Aliquat336 (15%, v/v), phase ratio (1:1, v/v), solvent ratio (2.5, v/v), agitation speed (100 rpm), and stirring time (120 min). The main driving force for this research work on the LA reactive extraction from the aqueous solution is the development of a suitable combination of extractants, organic solvents, and natural solvents that possesses high a nity with LA and, also, has lower toxicity with respect to LA-producing microbes.
