Abstract
The present paper deals with absorption of heavy ions of Pb2+, Cd2+ in water on potassium tetratitanate whisker (PTW). The effects of quantity of PTW, time and pH value on the absorption is studied. The test results show that the absorption efficiency of PTW increases with the quantity of absorbent, time and pH value. The absorption of Pb2+ and Cd2+ ions on PTW follows Freundlich's Equation. The property of PTW regeneration is also investigated in the present paper. The possibility of using PTW to treat industrial waste water containing heavy metal ions is discussed.
