Breakthrough modelling of glucamine functionalized PVDF nanofibrous adsorbent in a fixed-bed column for separation of boron from water
The performance of new nanofibrous chelating adsorbent, prepared by radiation induced grafting of glycidyl methacrylate onto electrospun poly(vinylidene fluoride) (PVDF) nanofibers followed by functionalization with N-methyl-D-glucamine, for removal of boron from aqueous solutions using a fixed-bed...
