Membranes prepared by radiation grafting of binary monomers for adsorption of heavy metals from industrial wastes

Preparation of Amidoxime Adsorbent by Radiation Induced Grafting of Acrylonitrile on Polyethylene Film and Its Application in Cr(VI) Removal

“…A number of researchers have studied single or binary monomer grafted PE film for heavy metal ion adsorption. [39][40][41][42] A polymeric adsorbent material based on PE was prepared by photo grafting of 2-(dimethylamino)ethyl methacrylate (DMAEMA) monomer on to a PE film and investigated for Cr(VI) removal. 43 Composite particles were synthesised using titanium oxide attached to PE films by plasma techniques and used for the removal of Cr(VI) from aqueous solutions in batch systems.…”

Preparation and properties of ion‐exchange membranes prepared by the radiation‐induced grafting of a styrene/acrylic acid comonomer onto low‐density polyethylene

“…The membrane had an affinity toward Zn 2þ ions rather than Cd 2þ and Pd 2þ ions, but in a mixture of the three metal ions, it had an affinity toward Pd 2þ ions. The ion-exchange membrane could be regenerated easily by treatment with 1M HNO 3 . It can be concluded that the prepared membrane could be used as ion exchanger to remove Cd 2þ , Pd 2þ , and Zn 2þ ions from wastewater.…”

“…The adsorbed metal ions can be easily desorbed from the membrane through soaking in 1M HNO 3 Table I shows that the desorbed membrane has a removal efficiency of 98% even after three cycles. Thus, the membrane can be used several times with high efficiency, and this makes it economically suitable for use.…”

In Separation and Purification

“…Because their chemical and physical properties may be tailored over a wide range of characteristics, the use of grafted and/or crosslinked polymers has found a permanent place in various fi elds. This includes separation processes [1,2] , energy conversion [3 -6] , solid state [3] , biomedical [7] , biological [8,9] , and environmental applications [10,11] . Among all polymers, the contribution of grafted and/or crosslinked polymers to the fi eld of separation and purifi cation has been tremendous due to their versatile involvement in a wide spectrum of commercial applications today; many more are being developed for the future in the chemical, environmental, pharmaceutical, and biotechnological industries [12] .…”
