Abstract

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.
