Summary:In this study, mesoporous MCM-41 has been modified by the incorporation of zirconium ion as a rapid, simple, and inexpensive method for modification. The adsorbent is characterized using powder X-ray diffraction and nitrogen adsorption-desorption isotherm data. The distribution coefficient of molybdenum ion on the mesoporous zirconium silicates has been enhanced with the increase of the zirconium in the framework of the adsorbent. The adsorption behavior of molybdenum on the Zr10MCM-41 adsorbent has been studied and the experimental adsorption isotherm is successfully described by the Langmuir model. The effect of pH and adsorption kinetics have also been studied by batch method. The adsorption capacity is very high in the pH range of 2-3 and decreases with increasing of the pH value.
