Rapid recognition and recovery of gold(III) with functional ligand immobilized novel mesoporous adsorbent

Awual, M. R.; Khaleque, M. A.*; Ferdows, M.*; Chowdhury, A. M. S*; Yaita, Tsuyoshi

The adsorbent was prepared by direct immobilization of 3-(3-(methoxycarbonyl)benzylidene)hydrazinyl)benzoic acid (MBHB) onto highly ordered mesoporous silica monoliths. The adsorbent enhanced the color formation by stable complexation as [Au(III)-MBHB] $^{n+}$ complexes during recognition and adsorption operations. The data revealed that the recognition system was in a one-step and, even ultra-trace Au(III) concentrations without using highly sophisticated instruments implied the adsorbent was novel.
