Incorporation of multi-walled carbon nanotubes in microspheres used as anion exchange resin via suspension polymerization

摘要: Amination of vinylbenzyl chloride-divinylbenzene (VBC-DVB) copolymers is an effective method for preparation anion-exchange resins. Conventionally, the starting polymer produced by chloromethylation a styrene–divinylbenzene copolymer that utilizes chloromethyl methyl ether, known carcinogen. An alterative approach to copolymerize chloride with divinylbenzene generate necessary VBC-DVB. This provides precise control over density ion-exchange groups. The regiochemistry methods was realized using solvent-ion exchange These resulting polymers were characterized variety techniques such as analytical titrations, transform infrared spectroscopy and thermal gravimetric analysis. Testing these breakthrough performed. results indicate anion exchangers have meaningful increase in stability commercial anionic beads. Resins containing MWCNTs achieved capacity value 323.6 meq/100 g than resins useful water desalination or treatment.
