“…Research fields involving NMDG are essentially metal removal by polyamine composites due to its chelating properties [8]. In 2012, Joshi and co-researchers [9] managed to synthesize glucaminium-based ILs for the removal of boron from water.…”

“…Previous research indicated that the chemical reaction can be the rate-limiting step [35,36]. In this work, N-methyl-D-glucamine (NMG), which is a more frequently used boron-specific complex ligand, was anchored on the membrane surface in order to pursue a shorter adsorption equilibration time [37].…”

“…In the case of ion exchange, the removal of boron occurs via its adsorption in specific resins, which are usually synthesized by means of macroporous cross-linked polystyrene resins, and functionalized by the N-methyl-D-glucamine (1-amino-1-deoxy-D-glucitol; NMDG) group achieving removal efficiencies up to 99% [23][24][25][26].…”

In the present work, the equilibrium, thermodynamics, and kinetics of boron removal from aqueous solutions by the adsorption on commercial magnesium oxide powder were studied in a batch reactor. e adsorption efficiency of boron removal increases with temperature from 25°C to 50°C.e experimental results were fitted to the Langmuir, Freundlich, and Dubinin-Radushkevich (DR) adsorption isotherm models. e Freundlich model provided the best fitting, and the maximum monolayer adsorption capacity of MgO was 36.11 mg·g −1 . In addition, experimental kinetic data interpretations were attempted for the pseudo-first-order kinetic model and pseudo-second-order kinetic model. e results show that the pseudo-second-order kinetic model provides the best fit. Such result suggests that the adsorption process seems to occur in two stages due to the two straight slopes obtained through the application of the pseudo-first-order kinetic model, which is confirmed by the adjustment of the results to the pseudo-second-order model. e calculated activation energy (E a ) was 45.5 kJ·mol −1 , and the values calculated for ∆G°, ∆H°, and ∆S°were −4.16 kJ·mol 1 , 21.7 kJ·mol −1 , and 87.3 kJ·mol −1 , respectively. ese values confirm the spontaneous and endothermic nature of the adsorption process and indicated that the disorder increased at the solid-liquid interface. e results indicate that the controlling step of boron adsorption process on MgO is of a physical nature.
