“…Consequently, the number of extractant molecules will also increase which promote complexation with SA at feed-organic interface. A similar trend of extraction was also found by Rahman et al (2019) who studied synergistic extractant mixture for dye extraction. In addition, the synergistic coefficient (SC) was also calculated as demonstrated in Table 1.…”

“…Petroleum based diluent achieved high extraction performance but the properties of the diluent are toxic, flammable, non-renewable and volatile in nature. Thus, the use of more environmentally product such as vegetable oil, sunflower oil and corn oil are applied in liquid-liquid extraction process as alternative that lead to the green and environmentally process (Rahman et al, 2019;Sulaiman & Othman, 2017).…”

“…Liquid-liquid extraction (LLE) process was carried out to study the feasibility of synergistic extractants on SA extraction process (Rahman et al, 2019). 10 mL of simulated succinic acid solution were mixed with 10 mL of organic solution (extractant in palm oil) in a 25 mL conical flask.…”

Bio-succinic acid (SA) is a new compound that will replace petroleum based succinic acid. The application of bio-based succinic acid is still restricted due to its excessive downstream processing cost. Liquid-liquid extraction (LLE) is one of the promising methods for the successful extraction of SA. Single extractant in the LLE formulation commonly had drawbacks of long extraction time and tiny loading capacity. The aim of this study is to create synergistic formulation to enhance the SA extraction performance. The diluent is fixed as palm oil as the characteristic shows that it is safer, renewable, and non-toxic to environment. Four different types of extractants including Aliquat 336, Trioctylamine (TOA), Tributylamine (TBA) and Tributyl-phosphate (TBP) was tested to find the best combination of synergist extractants. The result shows that almost 100 % of SA was extracted using synergistic mixture of TOA and Aliquat 336 at 0.2M with synergistic coefficient (SC) of 640. In conclusion, synergistic mixture has high potential to extract SA

“…Aliquat 336 shows selectivity for Cu(II) in moderate to strong acidic solutions, but the extraction performance is inferior to that of LIX 63 and Cyanex 301 [15]. Compared to a single extractant alone, higher extraction performance can be obtained by using a mixture of extractants [16][17][18][19]. Several mixtures of extractants have been reported for Cu(II) [19][20][21][22].…”

The smelting reduction of spent LIBs produces metallic alloys containing Co, Cu, Fe, Mn, and Ni. These metallic alloys can be completely dissolved by 2 M HCl solution containing H2O2 as an oxidizing agent. Extraction of the leaching solution with D2EHPA results in a Fe(III) free raffinate. In this work, solvent extraction experiments were performed with a mixture of Aliquat 336 and LIX 63 to separate Cu(II) from the Fe(III) free raffinate. This mixture showed selectivity for Cu(II) over Co(II), Mn(II), Ni(II), and Si(IV). The mixture of 0.3 M Aliquat 336 and 0.2 M LIX 63 had the highest synergistic coefficient for the extraction of Cu(II) from the solution. The Cu(II) in the loaded mixture was easily stripped by weak sulfuric acid solution, which facilitates the recovery of copper sulfate from the stripping solution. McCabe-Thiele diagrams for the extraction of Cu(II) by the mixture and for the stripping with sulfuric acid solution were constructed. Three stages of counter-current extraction and stripping experiments verified that only Cu(II) was completely extracted, and the purity of Cu(II) in the stripping solution was higher than 99.9%. Considering the selectivity and easy stripping of Cu(II) from the loaded organic, this mixture can be employed in real operation for the recovery of valuable metals from the leaching solutions of spent LIBs.
