摘要：

Mono-, di, and triamino ligands fixed on SBA-1 mesoporous silica capture chromate and arsenate effectively in a fashion where the saturation stoichiometries (Cr/N and As/N) depend on the type of ligand. Extraordinary adsorption capacities were achieved: 211 and 263 mg/g-adsorbent for chromate and arsenate, respectively.
