In this study, mesoporous MCM-41 has been modified by supporting of lead hexacyanoferrate (PbHCF) as a new adsorbent for strontium. The lead hexacyanoferrate-loaded mesoporous MCM-41 (PbHCF-MCM-41) was characterized using powder X-ray diffraction (XRD) and nitrogen adsorption-desorption isotherm data, infrared spectroscopy, scanning electron microscopy coupled with energy dispersive X-ray (SEM-EDX) and its strontium adsorption performance in aqueous solution was investigated. The effect of the various parameters like contact time, temperature, the initial pH value of the solution, and the initial concentration of the strontium ion on the adsorption efficiencies of PbHCF-MCM-41 have been studied systematically by batch experiments. Adsorption isotherm of PbHCF-MCM-41 was studied and the fitted results indicated that the Langmuir model could well represent the adsorption process. The maximum adsorption capacity of Sr2+ onto PbHCF-MCM-41 was found to be 97.09 mg center dot g(-1).
