摘  要：
通过间歇试验研究了羟基磷灰石(HAP)和骨炭(BC)对Pb~(2+)和Cd~(2+)吸附-解吸特性的差异,并借助红外光谱技术(FTIR)研究了HAP和BC对Pb~(2+)、Cd~(2+)吸附机制上的差异。结果表明,HAP和BC对Pb~(2+)和Cd~(2+)的吸附过程与Henry型和Freundlich型等温方程均具有较好拟合性,且BC对Pb~(2+)的吸附固定能力及吸附速率均明显高于HAP,而HAP对Cd~(2+)的吸附固定能力及吸附速率高于BC。

摘  要：
It was investigated about the different characteristics of Pb~(2+) or Cd~(2+)adsorption or desorption onto hydroxyapatite(HAP) and bone charcoal(BC) through batch experiment,furtherly,FTIR were used to explore the mechanisms underlying that.The results revealed that the adsorption of Pb~(2+)and Cd~(2+)onto HAP and BC fitted well with both Henry and Freundlich isotherm model,BC had much higher efficiency to remove Pb~(2+)from aqueous solution compared with HAP,besides,the Pb~(2+)could be more quickly adsorbed onto BC than that onto HAP. But it was opposite for the Cd~(2+)adsorption with the much higher removal efficiency and adsorption rate being found on HAP.
