“…The highest extraction efficiency of 74.7% was observed for the ATPS containing (NH 4 ) 2 SO 4 . Compared with the previous studies summarized in Table 1, this result is significantly higher than that for other ATPS based on polyethylene glycol 24,25 but lower than some ATPS based on octyl phenol ethoxylate. 23 The second-highest extraction was achieved for the MgSO 4 system.…”

“…They found that Pb from lead dithizone complex was not extracted in the Triton phase even though lead (Pb(II)) from a metal mixture (Hg, Bi, and Pb) was completely extracted at pH 8.9. In addition, Kaustab Ghosh et al studied the separation of no-carrier-added (NCA) 203 Pb (lead radionuclide) from proton irradiated nat Tl 2 CO 3 target and found that about 60% of NCA 203 Pb was extracted by using an ionic liquid, 1-butyl-3-methylimidazolium chloride ([bmim]Cl), and K 2 HPO 4 salt ATPS system. To the best of our knowledge, there is only one report on using aqueous biphasic systems based on polyethylene glycol, namely, PEG1500/(NH 4 ) 2 SO 4 and PEG1500/NaCl, to extract lead ions .…”

Lead ions are environmental pollutants often present in very low concentrations, which makes them difficult to detect and, thus, present problems for environmental monitoring. In this study, we examined the performance of aqueous biphasic systems based on polyethylene glycol (PEG, molecular mass of 4000 g mol −1 ) with ammonium sulfate (NH 4 ) 2 SO 4 , magnesium sulfate (MgSO 4 ), sodium sulfate (Na 2 SO 4 ), and trisodium citrate (Na 3 C 6 H 5 O 7 ) for the separation of lead(II) ions from aqueous solutions. We investigated the effects of salt types and the ratio of PEG4000 to salt on the extraction efficiency of lead(II) removal at constant temperatures of 303 K and 0.1 MPa. Additionally, we determined the cloud points (solubility equilibrium curve) and tie-lines for four ternary systems comprising PEG4000, water, and salt (either (NH 4 ) 2 SO 4 , MgSO 4 , Na 2 SO 4 , or Na 3 C 6 H 5 O 7 ) under the same conditions. A maximum lead(II) extraction efficiency of 74.4% was achieved using the PEG4000/(NH 4 ) 2 SO 4 system with a mass fraction ratio of PEG4000 to (NH 4 ) 2 SO 4 of 0.2:0.12. This outcome highlights the significant potential of utilizing aqueous biphasic systems based on PEG4000 to separate lead(II) from aqueous solutions efficiently.

“…Since their properties can be adjusted by their structural design according to people’s needs, they are considered to be fascinating “designable” chemicals, “future solvents” [ 24 ], and “panacea” solvents [ 25 ] that can solve many bottleneck problems across various domains. ILs show high extraction capacity for plenty of metal ions, such as nickel [ 26 ], palladium [ 27 ], and lead [ 28 ]. However, ILs are rarely investigated for use in soil remediation because the commonly used ILs, imidazolium- and pyridinium-based ILs, are not as green as desired.…”

To reduce contamination levels in Cd-contaminated paddy soil while retaining soil characteristics, we have studied the Cd-removing ability of 15 different amino acid-based ionic liquids, which are considered to be green solvents, as soil washing agents and their impact on soil. The results indicated that the glycine hydrochloride ([Gly][Cl]) removed the most Cd, and under optimized conditions could remove 82.2% of the total Cd. Encouragingly, the morphology of the soil had not been significantly changed by the washing process. After the soil was rinsed twice with water and the pH was adjusted to 6.2 by adding Ca(OH)2, the germination index of the rice increased by 7.5%. The growth of the rice was also stimulated, with lengths and weights of the rice plants increasing by 56% and 32%, respectively, after two weeks. These experiments demonstrate that amino-acid-derived ionic liquids can be promising soil-washing agents of Cd-contaminated paddy soil.
