Boron is a weakly-ionized species, which is hard to be removed completely by conventional water filtration processes for ultrapure water, such as ion exchange, reverse osmosis technologies. Alternatively, polymer based chelating agents are of great interest for boron removal due to their high boron adsorption capacity, provided by multiple hydroxyl groups. Here, core-shell type polymer particles were prepared via surface initiated polymerization to accommodate more N-methyl-D-glucamine (NMDG) groups. The core polymer beads were prepared though suspension polymerization of vinylbenzyl chloride (VBC) and divinylbenzene (DVB), and poly(glycidyl methacrylate) (PGMA) chains were grown from the core particles by ATRP. The grafted chain length was controlled by polymerization time, and their boron adsorption capacity was investigated after the functionalization with (NMDG). |
