研究了壳聚糖表面修饰碳纳米管（PBA/CS/CNTs）对水溶液中铯和锶的去除效果。实验数据与Freundlich方程和Redlich-Peterson模型拟合良好。吸附动力学符合拟二阶，限速步骤主要由膜扩散控制。吸附剂对Cs+/Sr2+的最大吸附量为219.8/205.1 mg g−1。研究表明，PBA/CS/CNTs可用于处理铯和锶污染的水。
The removal of cesium and strontium from aqueous solutions using chitosan surface-decorated carbon nanotubes which contains Prussian blue analog (PBA/CS/CNTs) was performed. The experimental data was fitting well with Freundlich equation and Redlich–Peterson model. Sorption kinetic was agreed with pseudo-second-order, and the rate limiting step was mainly controlled by film diffusion. The maximum Cs+/Sr2+adsorption capacity of adsorbents was 219.8/205.1 mg g−1. The study indicated that PBA/CS/CNTs can be used for the treatment of cesium and strontium contaminated water.
