For removal of radioactive Cs+ in aqueous solution, MIL-125 based MOF materials was functionalized with copper ferrocyanide (abbreviation as MIL-125/CuFC). The adsorption capacities was achieved at 174.79 mg/g via the Langmuir isotherm model. However, behavior of Cs+ adsorption was fitted better to Freundlich isotherm model. Through the kinetic adsorption tests, it is confirmed that the adsorption was reached at equilibrium very quickly and followed the pseudo-second order reaction. The MIL-125/CuFC has also a high adsorption capacity over a wide pH range. In addition, It has good properties as a adsorbent such as high specific surface area and thermal stability by SEM, FT-IR, BET and TGA analysis. Therefore, the MIL-125/CuFC was synthesized successfully for the removal of Cs+ in aqueous solution.
