Sup porting of potassiu m lead hex acyanofe rrate on m esoporous MCM-۴۱ as strontium adsorben t: isotherm, kinetic and ther modynamic studies

The m anagement of radioactive wastes has become a major concern, particu larly with regard to the release of radioactive materials in the environment. Liq uids may b e decontaminated using solid sorben ts, that the radionuclide s being concentrated un der smaller volumes of solid residues [۱]. The most frequently used ag ents for precipitation of Cs and Sr radionuclid es are transition metal hexacyanoferrate (II, III) which exhibit high sor ption selectivity toward these radionuclides and especially t hat from salinity solution [۲].In this work, mesoporou s MCM-۴۱ was ch osen for supporting potassium lead hexacyanoferrate (KPbCF) to prepare a ne w Sr-selective material.
