A chelating fabric was prepared by graft polymerization of glycidyl methacrylate (GMA) onto a nonwoven fabric, followed by attachment reaction of N-methyl-D-glucamine (NMDG) using an organic solvent-free process. The graft polymerization was performed by immersing the gamma-ray pre-irradiated fabric into the GMA emulsion, while the attachment reaction was carried out by immersing the grafted fabric in the NMDG aqueous solution. The chelating capacity of the chelating fabric prepared by reaction in the NMDG aqueous solution without any additives reached 1.74 mmol/g, which further increased to above 2.0 mmol/g when surfactant and acid catalyst were added in the solution. The boron chelation of the chelating fabric was evaluated in a batch mode. Fourier transform infrared spectrophotometer (FTIR) was used to characterize the fabrics. The chelating fabric can quickly chelate boron from water to form a boron ester, and a high boron chelating ability close to 18.3 mg/g was achieved in the concentrated boron solution. The chelated boron can be eluted completely by HCl solution. The regeneration and stability of the chelating fabric were tested by 10 cycles of the chelation-elution operations. Considering the organic solvent-free preparation process and the high boron chelating performance, the chelating fabric is promising for the boron removal from water.

This study describes an efficient and solvent-free method for the regioselective production of L-lysine ammonium epsilon-carbamate by ball-milling L-lysine under an atmosphere of CO<sub>2</sub>. The regioselective formation of L-lysine ammonium epsilon-carbamate by this mechanochemical approach was confirmed by a complete analytical study, including <sup>1</sup>H-<sup>13</sup>C and <sup>1</sup>H-<sup>15</sup>N CP MAS NMR measurements as well as liquid NMR analysis, powder X-ray diffraction, thermal analysis, and elemental analysis. Time of milling, rotational speed, milling material, and liquid assistants were screened, while the reversibility of the process was assessed. This milling approach was compared with the syntheses in aqueous solution and in the solid-state without agitation. In addition to be regioselective, the synthesis by solvent-free mechanochemistry was found to be much faster than the other approaches while producing lot less waste.
