| 英文摘要 | Adsorption/desorption in a new Zn(II)-TiO2 adsorption system was investigated at different particle concentrations (C-p). TEM, SEM and XRD analyses revealed that the TiO2 particles were an aggregation of nano-sized (approximately 10 nm) pure anatase-type TiO2. Adsorption experiments were carried out with particle concentrations of 100, 400 and 1000 mg/L, and their adsorption isotherms were found to decline successively, showing an obvious C-P effect. Desorption experiments indicated that adsorption in this system was irreversible, and the irreversibility increased with increasing C-P. These phenomena could be explained by the MEA (metastable equilibrium adsorption) theory and the C-P effect could be modeled well with an MEA-Freundlich-type CP effect isotherm equation. This study may help understand environmental behavior of contaminants on ultrafine natural particles. |
