Highly functionalized microporous polyurethane foam bearing aminothiacalix [۴] arene for removal of heavy metal such as Se(Ⅳ), Co(Ⅱ), Pb(Ⅱ)from aqeous solution

In this study, modified polyurethane soft foam (MPUF) containing p-amino thiacalix[۴]arene(ATC۴A) carriers were used to enhance metal cation adsorption efficiency from water compared tocommonly used polyurethane foam (PUF). Metal ions were more prone to bind to the MPUF carrierthan the PUF carrier. Functional groups in macrocyclic cavity are responsible for chelation withmetals. The MPUF was characterized by using infrared spectra spectroscopy, scanning electronmicroscope (SEM). The heavy metal removal effeciency up to ۹۰% was achieved at optimum pH of۸. Based on these findings, it can be concluded that this new MPUF composite material holdssignificant promise as a potent sorbent for wastewater treatment backed by its excellent performance,and outstanding reusability.
