Abstract

A facile, green strategy is explored to obtain mesoporous titanium glycolate (Ti(OCH₂CH₂O)₂) via a one-pot hydrothermal reaction. The mesoporous Ti(OCH₂CH₂O)₂ nanomaterials take on a three-dimensional V-Type stripe structure with a specific surface area of 246.5 m² g^-1 and present an excellent adsorption capacity of toxic heavy metal ions in aqueous solution, 225.73 mg g^-1 for Pb(ii), 131.93 mg g^-1 for As(v) and 156.01 mg g^-1 for As(iii) with fast adsorption rates. The removal mechanism was found to derive from the electrostatic interaction or coordination interaction between Ti(OCH₂CH₂O)₂ and heavy metal ions in aqueous solution since the mesoporous materials display a pH-dependent effect for arsenic removal.
