| 摘 要： | 采用缺氧控温法,在200、400、600和800℃条件下制备鸡粪生物炭(BC200、BC400、BC600和BC800),利用比表面积及孔径分析仪(BETacceleratedsurfaceareaandporosimetrysystem)、扫描电镜(scanningelectron microscopy)、透射电镜(transmission electron microscope)、傅里叶红外光谱仪(Fourier transform infrared spectroscopy)等对其理化性质和结构特征进行表征,并研究了鸡粪不同温度处理下生物炭对水体和土壤中Cd、Pb污染修复效果。结果表明,鸡粪生物炭灰分含量、pH值、BET比表面积及孔径随热解温度的升高而增加,表面出现大量无规则的孔隙结构,且以介孔为主,而生物炭产率则随温度升高而显著降低(P0.05)。鸡粪生物炭对Cd2+、Pb2+的吸附分为快速吸附和慢吸附2个阶段,Elovich模型能更好地模拟Pb2+、Cd2+的动力学过程,平衡时最大吸附量分别达到52.02 mg/g (BC600)和242.59 mg/g (BC800)。添加鸡粪生物炭显著提高了土壤pH值(P0.05),而TCLP提取态Pb、Cd含量降低,最大较对照分别降低16.5%和14.5%。与对照相比,鸡粪生物炭不同程度上降低了Pb、Cd弱酸提取态、可还原态以及可氧化态比例,其残渣态比例则分别增加了5.49%～15.14%和2.51%～6.30%。综上所述,鸡粪生物炭对重金属Pb、Cd具有较强的钝化效果。
