Abstract:Synthesis and identification of some thermo-responsive hydrogel metal absorbents based on Schiff base modified PNIPAM is described. PNIPAM hydrogel is produced through conventional free-radical polymerization method. The hydrogel is amino modified with different amines and then treated with various aldehydes to make polymeric Schiff-bases supposing to utilize as an absorbent for Cu salt. Characterization of the as-prepared hydrogels was performed properly and confirmed the corresponding structures. Kinetic and… Show more
“…The addition of comonomers helps to enhance their adsorption capacity or induce stimulus-responsive behavior, which supports the selective and greater adsorptive property of microgels. For example, Ghasemi et al 106 synthesized a P(NIPr)-based microgel and used it for the adsorption of copper( ii ) ions from water. The synthesized microgels adsorb copper( ii ) ions due to the presence of polar amide groups in their structure.…”
Adsorptive property of microgels is reported briefly in this review. Morphology and synthetic methods of adsorbent (microgels) are described. Various adsorption isotherms and kinetic models of adsorption are also discussed.
