摘要

研究了腰果壳(CNS)表面修饰纳米零价铁(nZVI)复合材料对镉离子的去除效果。2 g/l CNS-nZVI的去除率为98%。吸附量为35.58 mg/g。Freundlich等温线(R2 = 0.9769)和拟二级吸附动力学数据拟合良好。实验证明CNS-nZVI对Cd(II)具有较高的去除率。

Superhigh Adsorption of Cadmium(II) Ions onto Surface Modified Nano Zerovalent Iron Composite (CNS-nZVI): Characterization, Adsorption Kinetics and Isotherm Studies
The efficiency of surface modified nanoscale zerovalent iron (nZVI) composite by cashew nut shell (CNS) was tested for the removal of cadmium ions from the aqueous solutions. 2 g/l CNS-nZVI was efficient for 98% removal. The adsorption capacity was 35.58 mg/g. The Freundlich isotherm (R2 = 0.9769) and the pseudo-second order adsorption kinetics data fitted well. This proved CNS-nZVI has a high removal efficiency for Cd(II) from aqueous solutions.
