Encapsulation of elemental sulfur inside of carbon nanotubes is one of the best solutions to face the Lithium–Sulfur batteries challenges to get successful commercialization. In this work, the first parametric study of the capillary drawing-in dissolved materials in low surface tension solvents accompanying ultrasonic method is reported which has l...

In this study, for the first time the organic gas steam-liquid extraction (OGS-LE) method is used as a simple, efficient and scalable to industrial application technique for the extraction and separation of uranium (VI) from aqueous samples. OGS-LE is done by a special handmade extraction cell. In this method, the organic solvent vapor produced in...

Polymer inclusion membranes (PIMs) have received much attention as a greener method than other liquid membranes for the separation of a great number of chemical species. The expected horizon of industrial applications besides the advantages of greener characteristics of PIMs than other liquid membranes and solvent extraction methods, have resulted...

The present paper describes the preparation of a novel composite included the phenobarbital imprinted polymer of aniline (PB-MIP-PANI) and the layered graphene oxide (GO). The process involved the precipitation-polymerization of the functional monomer by using ammonium persulfate as an initiator. FT-IR, TGA, EDX, and FE-SEM techniques were used for...
Article
Recently, it has been shown that a polymer inclusion membrane (PIM) containing 50 wt% of polyvinyl chloride (PVC) and 50 wt% bis(2-ethylhexyl)phosphoric acid (D2EHPA) is able to extract efficiently Bi(III) from sulfate solutions. The advantages of the transport processes motivated us to evaluate the potential of the proposed PIM for the recovery of...
Preprint
A polymer inclusion membrane (PIM) composed of 50 wt% poly(vinylidenefluoride-co-hexafluoropropylene) (PVDF-HFP) as its base polymer, 40 wt% Aliquat® 336 as its extractant and 10 wt% dibutyl phthalate (DBP) as plasticizer provided efficient extraction of vanadium(V) from its sulfate solutions adjusted to pH 2.5. It was suggested that V(V) was extra...

... They reported that as a result of contact with water, a partial loss of the carriers has been observed (largest in the case of a PIM AlqCl-CTA) and that the nature of carrier has a great influence on the morphology of the membranes (AlqCl was more miscible with the polymer matrix, whereas other carriers formed nano-spheres on the surface of the PIMs). It has been shown that Aliquat 336 is also suitable for removing V(V) ions from spent alumina hydrodesulfurization catalysts, suggesting its future applicability on a larger scale for real waste/wastewater treatment [37]. Currently, studies are also carried out to optimize the composition of PIMs containing Aliquat 336 in terms of their various environmental applications related to the transport of As(V) ions with the use of response surface methodology (RSM) coupled to the Derringer's desirability function (DF) [101]. ...
... One of the most frequently used plasticizers of polymer inclusion membranes in recent years is 2-NPOE, which is characterized by high dielectric constant and low viscosity [38,46,49]. It is known that these parameters influence the stability of complexes formed by metal ions in the membrane phase, but the performance of the plasticizer also depends on the properties of other components of the membrane. ...
... Phenobarbital is a barbiturate drug that has sedative and hypnotic properties. It is a widely used drug in epilepsy and insomnia treatment (Velayati et al. 2022;Zadaliasghar et al. 2020;Raol et al. 2005). The PHEN interacts with the GABAa receptor potentiating the depression action mediated by this receptor. ...
