Due to the narrow range between boron necessities and toxicity in the environment, there is a high interest in the design of effective boron remediation procedures. We have previously reported a promising boron adsorption material based on the affinity of boron aqueous species for cis-diol groups that were anchored on different mesoporous silica matrices. However, the small particle size of these systems makes them difficult to be applied on real remediation situations. In this context we report herein a novel system for boron adsorption from aqueous solutions in which the high boron affinity for functionalized mesoporous materials is combined with the mechanical properties of ceramic foams as macroscopic supports. The efficiency of these new composites for boron removal is very high and comparable with the parent microparticulated adsorbent. (C) 2015 Elsevier B.V. All rights reserved.
