Preparation method of novel stabilized green rust and application of novel stabilized green rust in selective adsorption of cesium ions

The preparation method is simple, and the required raw materials are wide and easy to obtain. Through the steps of vanadium and iron element combination, low-temperature plasma activation and synchronous internal doping of phosphate radicals and oxalate radicals, preparation of the novel stabilized patina material is achieved. The prepared stabilized patina material is large in cesium ion adsorption capacity (the maximum adsorption capacity is 523 mg/g) and high in cesium ion selectivity, and the cesium selectivity coefficient is 14.26. 本发明制备方法简单，所需原料广泛且易得。通过组合钒和铁元素、低温等离子活化、磷酸根和草酸根同步内掺步骤，实现新型稳定化绿锈材料制备。所制备的稳定化绿锈材料不仅铯离子吸附容量大（最大吸附容量为523mg/g）且铯离子选择性高，铯选择性系数为14.26。
