Catechol and gallol group has a high binding affinity towards metal ions through metal ion coordination and hydrogen bonding. Here, we focus on functionalizing the appropriate commercial resin to make high-performance heavy metal ion absorbers. So, first time, we synthesized dihydroxystyrene and trihydroxy styrene polymer on the surface of Merrifield's resins using the reversible addition−fragmentation chain-transfer (RAFT) polymerization followed by the reduction method. In the RAFT method, we can enhance the functional group on the surface area based on monomer insertion on resin during polymerization. We investigated the removal capacity of lead, copper, zinc, magnesium, and silver ions from the aqueous solution. The polymerization yields were quantitative. |
