羟基磷灰石纳米棒的合成及其吸附行为研究

Hydroxyapatite, the mineral constituent of human hard tissues (bones, teeth, etc.), is an important raw material for the artificial bone graft due to its biocompatibility and biodegradability. In this paper, we synthesize and characterize the nanorods via hydrothermal synthesis in an aqueous system, and study the sorption properties of these hydroxyapatite nanorods. The naorods are about 20 nm in diameter and 200-400 nm in length. We investigate the kinetic sorption of the aqueous zinc ions adsorbed on the synthesized HA nanorods and find that HA nanorods have a fine removal for aqueous zinc ions as well as their Langmiur type adsorption isotherms.
