“…3 Among all, adsorbents obtained by radiation-induced graing and subsequent functionalisation provide attractive materials for more effective removal of ionic pollutants from water and wastewater. 16 Removal of boron by brous adsorbents graed with glycidylmethacrylate (GMA) onto various bers such as polypropylene and viscose bers, 9 nylon-6 bers, 17 polyethylene (PE) 18 bers and PE non-woven fabric 19 followed by NMDG treatment was reported recently. Moreover, the graing reaction can be initiated from monomers in different phases and temperatures allowing either surface or bulk modication of polymer substrates depending on the reaction parameters which can be tuned to obtain the desired compositions.…”

A new adsorbent containing boron-selective groups was prepared by radiation induced grafting of vinyl benzyl chloride (VBC) onto nylon-6 fibers followed by functionalisation with N-methyl-D-glucamine (NMDG). The density of glucamine loaded in the adsorbent was tuned by optimisation of the reaction parameters such as NMDG concentration, reaction temperature, reaction time and degree of grafting using response surface methodology (RSM) employing Box-Behnken design (BBD). The optimum parameters for achieving the maximum glucamine density (1.7 mmol g À1 ) in the adsorbent are 10.6%, 81 C, 47 min and 121% for the NMDG concentration, reaction temperature, reaction time and degree of grafting (DG), respectively. The deviation between the optimum experimental and predicted glucamine density is found to be 1.2% suggesting the reliability of RSM in predicting the yield and optimising the functionalisation reaction parameters. The chemical composition, morphology and structure of the NMDG-containing fibrous adsorbent were studied using Fourier-transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. The thermal properties were determined using differential scanning calorimetry (DSC) and the thermal stability was evaluated by thermogravimetric analysis (TGA). Considering the physico-chemical properties of the fibrous adsorbent and the preliminary results of boron adsorption, it can be suggested that this adsorbent is a promising candidate for boron removal.

“…Radiation induced graft copolymerization (RIGC) is an interesting technique for introducing functional groups to preformed polymers in various physical forms (fibers, films and beads) using polar monomers and hence it is appealing for preparation of a variety of functionalized adsorbents . Fibrous chelating boron adsorbents obtained by grafting glycidyl methacrylate (GMA) onto a polyethylene coated polypropylene non‐woven fabric and nylon‐6 fibers have been reported and adsorption behavior investigated.…”

BACKGROUND The performance of newly prepared fibrous boron selective adsorbent was investigated via equilibrium isotherms, kinetics and thermodynamics of boron adsorption from aqueous solutions. The adsorbent was obtained by radiation induced graft copolymerization (RIGC) of vinyl benzyl chloride (VBC) onto nylon‐6 fibers followed by chemical treatment with N‐methyl‐D‐glucamine (NMDG). RESULTS The effect of solution pH on the boron adsorption capacity was investigated. The equilibrium adsorption data was fitted to the Langmuir, Freundlich and Redlich–Peterson isotherms, with the experimental data best fitting the Redlich–Peterson model. The kinetic data analyzed using the intra‐particle diffusion model indicated that adsorption onto the fibrous chelating adsorbent is governed by a film diffusion mechanism. The thermodynamic adsorption parameters including the Gibb's free energy change (ΔGo), enthalpy change (ΔHo) and entropy change (ΔSo) were determined and the results indicated that adsorption onto the fibrous adsorbent occurs spontaneously. CONCLUSION The high adsorption capacity and rapid kinetics suggest that the newly prepared fibrous adsorbent could have strong potential for boron removal from aqueous solutions. © 2015 Society of Chemical Industry

“…For the past decades glycidylmethacrylate (GMA) is considered to be the most widely used precursor monomer for graft polymerization, as the epoxy group can be modified easily into functional groups [34][35][36]. However, too much high D g would lead the brittleness of grafted material.…”
