Prussian blue encapsulated in alginate beads reinforced with highly dispersed carbon nanotubes were prepared for the safe removal of cesium ions from aqueous solutions. Equilibrium and kinetic studies were conducted using different models and the goodness of mathematical fitting of the experimental data on the adsorption isotherms was in the order Langmuir>Freundlich, and that of the kinetic models were in the order of pseudo second order>pseudo first order. Fixed bed adsorption column analysis indicated that the beads can be used for large scale treatment of cesium contaminated water.
普鲁士蓝被封装在海藻酸钠珠粒中，并用高度分散的碳纳米管增强，用于从水溶液中安全去除铯离子。使用不同的模型进行了平衡和动力学研究，并且对吸附等温线的实验数据的数学拟合的良好程度的顺序为朗缪尔>弗伦德利希，而动力学模型的顺序为伪二级>伪一级。固定床吸附柱分析表明，这些珠子可用于大规模处理含铯污染的水。
