桉树遗态结构HAP/C复合材料制备及表征
|
摘要
以桉树为植物模板,循环浸渍在磷酸氢二铵和氢氧化钠溶液中,得到一种新型的桉树遗态结构羟基磷灰石/碳(HAP/C)复合材料。通过X射线衍射仪、红外光谱和扫描电镜等手段对所制备的复合材料进行表征。结果表明:桉树遗态钙羟基磷灰石/碳复合材料(PBGC-HAP/C-E)主要由HAP和C组成,复合材料很好保留了桉树天然多孔分级的遗态特征,比表面积为159.8m~2/g。考察了所制备复合材料对典型重金属离子的吸附能力,研究发现其吸附能力优于市售活性炭,为水环境重金属污染处理提供了一种新材料。
A porous biomorph-genetic composite of hydroxyapatite/carbon(PBGC-HAP/C)was prepared with eucalyptus wood template as a new sorbent.It was characterized by using X-ray diffraction(XRD),infrared absorption spectrum(FT-IR)and scan electronic microscope(SEM).A series of analytical results indicated that PBGC-HAP/C-E was mainly consisted of hydroxyapatite(HAP)and carbon.Its BET surface area was determined to be 159.8 m2/g.The adsorption capacity of prepared composite for heavy metal ions was investigated and compared with activated carbon and fly ash under the same experimental condition.The results showed that the composite exhibited excellent adsorption performance.The adsorption capacity for heavy metal ions was far more than that of activated carbon.PBGC-HAP/C-E can be used as a potential substitute of activated carbon for heavy metal ions adsorption in waste water.
