Paper Title:
Influence of Sol Compositions on Boron Adsorption by Boron-Selective Hybrid Gels
  Abstract

Hybrid gels with boron-chelating groups were prepared using bis(trimethoxysilylpropyl)amine (TSPA) and the precursors synthesized from (3-glycidoxypropyl)trimethoxysilane (GPTMS) and N-methylglucamine (MG). Boron adsorption by the hybrid gels and a commercial boron-selective resin D564 were compared. The experimental results demonstrated that sol compositions have a great effect on the boron adsorption by the hybrid gels. Changing the sol compositions is a convenient way to adjust the adsorption capacity of the hybrid gels. The highest boron adsorption amount of the hybrid gels was found to be 1.54 mmol g-1, higher than that of the commercial resin D564 (1.39 mmol g-1). The hybrid gels reported in this study are easy to prepare, having a higher adsorption capacity and a good mechanical strength.
