Design and fabrication of an innovative and environmental friendly adsorbent for boron removal.

摘要: Boron can pose adverse effects on human beings and plants species. It exists in various water environments is difficult to be removed by conventional technologies. In this study, an efficient environmental friendly sorbent was fabricated the functionalization of a natural biopolymer, chitosan, with N-methylglucamine through atom transfer radical polymerization. The SEM BET studies revealed that had rougher surface more porous structure than chitosan. At optimum neutral pH, maximum sorption capacity as high 3.25 mmol/g, much higher commercial boron selective resins (e.g., Amberlite IRA-743) many other synthesized sorbents. Almost 90% occurred within 8 h equilibrium established 12 h, which well described intraparticle diffusion model. presence sodium chloride nitrate no effect removal. concentration seawater could reduced less 0.5 mg/L from 4.8 when dosage 1.2 g/L used. therefore concluded technology study promising for removal aqueous solutions.
