Abstract

Fibrous sodium titanate was prepared with the reaction of Ti plates, NaOH and H 2 O 2 at 80°C for 24h. Sodium titanate was characterized by XRD, FT IR, SEM. Sodium titanate prepared exhibited excellent a dsorption capability for neutral red (NR), methylene blue (MB), malachite green (MG) and crystal violet (CV), and the saturated adsorption capacities were 323.42, 235.18, 261.38 and 206.92 mg/g at 25°C, respectively. The pseudo second order kinetic model a nd Langmuir model could well describe the adsorption of NR, MB, MG and CV. This work is of great significance for applications of sodium titanate as a promising adsorbent material for dyeing water purification..
