Grafted polymeric organogel using low molecular weight gelator as an effective medium for expulsion and purification of cationic dyes and organic pollutants from contaminated surface water

Polymeric organogel as an effective approach for eradication of heavy metal ions As, Pb, Cd, and Cr from the surface of groundwater through adsorption stratagem

“…The adsorbent was prepared using the following procedure as reported elsewhere 29 wherein 0.2 mM of PVA was allowed to dissolve in 15 mL of DMSO in the presence of catalyst p-TSA for about half an hour at 80 C with continuous stirring. Followed by the addition of 0.68 mM AMPS along with 0.31 mM of crosslinker MBA with the oxidative agent APS of 0.017 mM which was then left for stirring until the formation of gelation occurs after 6 hours (Figure 1).…”

“…The organogel has been proven as an effective adsorbent after the expulsion of cationic dyes and solvents as reported in previous work. 29 However, the adsorbent in this work (based on the most efficient one from previous work) has been focused solely on the removal of heavy metals from aqueous solutions without departing any secondary pollutant reflecting its efficacious usage by creating a strong interactive force between active sites of the adsorbent and metal ions creating a cleaner and sustainable environment. Functional sites are of prime importance as they provide binding sites necessary for the removal of required species.…”

Aluminum Montmorillonite/Polyaniline Hybrid Composite-Based Organogels for the Expurgation of Carcinogenic Chlorophenols and Congo Red Dye from Defiled Water Sources

“…Avoiding such limitations with a simple yet facile preparation method using nontoxic cost-effective materials with high efficiency, ease of productibility, and adaptiveness, adsorbents have been preferred for the removal of organic pollutants from waste resources. Various adsorbents such as polymers, − graphene, activated carbon, , metal–organic frameworks (MOFs), and metal oxide-based adsorbents , have been widely favored, while the current work focuses on nonconventional materials with polymers to form an effective adsorbent for the removal of organic dye as well as toxic phenols.…”
