摘要:In the present study, the removal of tetracycline (TC) from aqueous solution by titanate nanotubes (TNTs) was investigated. TNTs were synthesized by hydrothermal treatment of the commercial TiO2 particles. The morphology and structures of theas-prepared products were investigated by transmission electron microscopy, N-2 adsorption/desorption, Fourier transform infrared, and X-ray diffraction. Batch experiments showed that the removal of TC by TNTs was very fast in the first 60min, and then reached equilibrium after 180min. The removal efficiency of TC increased with the increase in the dosage of TNTs and the decrease of initial TC concentration. Initial pH also affected the removal process and the optimum initial pH was 5. The kinetic data were better described by the pseudo-second-order model than by the pseudo-first-order model. The equilibrium adsorption data were analyzed with three isotherm models (Langmuir model, Freundlich model, and Temkin model). The data were best fitted with the Langmuir isotherm model with correlation coefficient of 0.9947, corresponding to a maximum adsorption capacity of 113.6mg/g.
