  • 摘要: 本实验选用由芦苇秸秆制备的生物炭,通过研究吸附等温线、吸附动力学以及生物炭投加量和溶液pH对生物炭吸附Ni2+的影响,以确定其对水体中Ni2+的吸附特性.结果表明,Ni2+初始浓度在0.5—12 mg·L-1范围内,Langmuir模型能很好地描述生物炭对Ni2+的等温吸附规律,其理论饱和吸附量为12.10 mg·g-1,与实际饱和吸附量11.93 mg·g-1相近.生物炭对Ni2+的吸附动力学过程符合准二级动力学模型,通过颗粒内扩散方程可得具体吸附过程由膜扩散和内扩散共同控制.随投加量增加,生物炭对Ni2+的吸附量下降,而去除率则上升,当投加量 > 30 mg时,Ni2+的去除率接近100%.溶液pH值在1—12范围内,Ni2+的去除率随pH值的升高而增加,当pH > 10时,Ni2+的去除率同样接近100%.
    Abstract: Adsorption isotherm, kinetics and influcing factors such as biochar mass and solution pH were investigated to determine the adsorption characteristics of Ni2+ onto reed straw biochar in aqueous solution. The results showed that the adsorption isotherm of Ni2+ onto biochar could be well described by Langmuir model with Ni2+ concentration between 0.5 mg·L-1 and 12 mg·L-1, and the theoretical maximum adsorption was 12.10 mg·g-1, which was in good accordance to the experimental value (11.93 mg·g-1). The adsorption process could be well fitted by pseudo-second-order model, and through intraparticle diffusion model, the specific process was controlled by both membrane diffusion and internal diffusion. With increasing biochar mass, Ni2+ adsorption decreased but its removal rate increased. When the mass was above 30 mg, the removal rate approached 100%. In the pH range of 1—12, the removal rate of Ni2+ enhanced significantly with increasing pH in aqueous solution. When the pH was above 10, the removal rate also approached 100%.
