2026-09-15 Preparation Method and Application of Hierarchical Sodium Titanate Microtubes doi:10.57760/sciencedb.iga.01381 en This patent discloses the preparation method of hierarchical sodium titanate microtubes and their application in heavy metal wastewater treatment. Aiming at the problems of poor recoverability of traditional titanate nanomaterials and low adsorption capacity of large-size materials, micro-scale hierarchical sodium titanate microtubes are prepared by using tetrabutyl titanate as the raw material to synthesize titanium glycolate precursor via the polyol method, followed by a hydrothermal reaction in an alkaline solution. This material features a large specific surface area combined with a unique hollow structure, enabling rapid and high-capacity adsorption of lead ions with high selectivity and good pH adaptability. It can be conveniently recovered via membrane filtration and achieves a high lead ion removal rate, which can meet the national standard requirements for the discharge of lead-containing wastewater. hierarchical sodium titanate m; preparation method; heavy metal wastewater treatme; lead ion adsorption; tetrabutyl titanate 于洪文 PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
