Novel polyelectrolyte gels as absorbent polymers for nonpolar organic solvents based on polymerizable ionic liquids

Preparation and evaluation of a polymeric gel containing ionic liquid-functionalized MWCNTs as a novel class of organic solvent absorbent

“…All the organic solvent absorption measurements were similar to our earlier reports . A quantity of about 0.10 g of dried sliced gel was placed in four different organic solvents (carbon tetrachloride, toluene, chloroform, and dichloromethane) at room temperature.…”

“…This modification of MWCNTs, not only causes the polymerization becomes more easily on the surface, but also inserts the hydrophobic dissociable ionic groups into polymeric network that can improve the swelling capacity of ILMPGs in organic solvents. It should be noted that the effect of incorporation of the monomers with lipophilic ionic groups into polymeric gels on the organic solvent absorbency was investigated . In spite of the great achievements made in these studies, there are some limitations in these polyelectrolyte gels, in particular the formation of a polyelectrolyte gel with less effective network volume due to the presence of long alkyl chains in 1‐vinyl‐3‐alkylimidazolium tetrafluoroborate units.…”

“…All the organic solvent absorption measurements were similar to our earlier reports. 56 A quantity of about 0.10 g of dried sliced gel was placed in four different organic solvents (carbon tetrachloride, toluene, chloroform, and dichloromethane) at room temperature. After immersion for a predetermined time (12 h), we measured Q of the ILMPGs, which is defined by as the following equation:…”

Jacket-free stir bar sorptive extraction with bio-inspired polydopamine-functionalized immobilization of cross-linked polymer on stainless steel wire

“…The availability of functional monomers and cross-linkers with variable properties makes the cross-linked organic polymers applicable to different kinds of compounds [12,13]. In addition, both polar and nonpolar compounds can be extracted by polymers [14,15]. Cross-linked organic polymers have been applied in sample pretreatment methods such as miniaturized solid-phase extraction [14], solid-phase microextraction (SPME) [7] and stir-bar sorptive extraction (SBSE) [13].…”
