Extraction and recovery optimization of succinic acid using green emulsion liquid membrane containing palm oil as the diluent

Abstract

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

Membrane Purification Techniques for Recovery of Succinic Acid Obtained from Fermentation Broth during Bioconversion of Lignocellulosic Biomass: Current Advances and Future Perspectives

“…The optimized conditions for extraction of succinic acid (up to 71%) was 0.01 M Na 2 CO 3, at 1:3 treatment ratio, 0.7 M Amberlite LA2, 10% w/v Octanol and external solution of 2 [121]. However, using Response surface methodology, the optimized recovery conditions obtained approximately 40% of succinic acid in a study conducted by Jusoh et al [122]. At favorable conditions, 84% of succinic acid was recovered at a purity of close to 100%.…”

Zirconium and Hafnium Separation by Novel Green Emulsion Liquid Membrane Containing an Environmentally Benign Diluent

“…In addition, LEM use limited extractant quantities, low production costs, short operation time, high surface area for mass transfer, simple operation method, and can be operated continuously [11,12,15]. The diluent is an essential component in the composition of the LEM which represents the largest part of the LEM constituents and directly affects the stability of the membrane [16].…”

“…Due to the recent greater stringent environmental regulations [17], studies on extraction methods have directed to the more eco-friendly diluents (green diluents) such as vegetable oils [16]. The bio-degradability, nontoxicity, non-volatility, and inflammability with the other green features of the vegetable oils, like palm, sunflower, cotton, coconut, corn, and peanut oils make them a strong competitor for the traditional diluents [15][16][18][19]. Furthermore, the aliphatic properties of these vegetable oils and their low dielectric constant make them non-polar and immiscible with aqueous solutions [16].…”

“…Several studies were carried out to investigate the effectiveness of using vegetable oil as a green diluent with various extractants [12, [15][16][17][18][19]. [11] examined the efficiency of using some vegetable oils (sunflower, corn, and palm oil) as a diluent in the formation of LEM consisting of Aliquat 336 (carrier), Span 80 (surfactant) and NaOH (internal phase).…”
