Abstract

The prepared MCM-41 mesoporous material was synthesized into the new mesoporous material of Ti-MCM-41 by impregnation method, and the sample was characterized by infrared spectrometer. The adsorption of lead ions in solution was carried out by using Ti-MCM-41 as adsorbent. The effects of adsorbent dosage, initial mass concentration of lead ion, temperature and time on adsorption performance were investigated. The reaction kinetics model of Ti-loaded molecular sieves adsorbing lead ions conforms to the second-order kinetic model, and the reaction thermodynamics process conforms to the Langmuir thermodynamic model.
