Abstract:

In this paper, the adsorption of cerium on modified Mesoporous aluminosilicate (with Si/Al mole ratio of 10) was studied. The effects of pH, contact time, initial concentration of cerium on adsorption of cerium were investigated. The adsorption capacity was high in the pH range of 4-8 and decreases with decreasing of the pH value. The Langmuir and Freundlich isotherms were applied to represent the adsorption process. Both Langmuir and Freundlich isotherms fit the experimental data quite well. The Langmuir monolayer capacity of the adsorbent was 0.032 mmol.g-1.

Adsorption behavior of cadmium on modified mesoporous aluminosilicates

In this study, mesoporous MCM-41 has been modified by incorporation of aluminum ion asa rapid, simple and inexpensive method for modification. The adsorbent is characterized usingpowder X-ray diffraction and nitrogen adsorption-desorption isotherm data. The distributioncoefficient of cadmium ion on the mesoporous aluminosilicates has been enhanced with theincrease of the aluminum in the framewo...

Immobilization of Methyltrioxorhenium on Mesoporous Aluminosilicate Materials

The presented report focuses on an in-depth detailed characterization of immobilized methyltrioxorhenium (MTO), giving catalysts with a wide spectra of utilization. The range of mesoporous materials with different SiO₂/Al₂O₃ ratios, namely mesoporous alumina (MA), aluminosilicates type Siral (with Al content 60%-90%) and MCM-41, were used as supports for immobilization of MTO. The tested suppor...

Adsorption of Acid Dyes on Modified Mesoporous SBA-15: Comparison of Two Dyes

In this study, SBA-15-PAMAM mesoporous Nano-adsorbent was synthesized, characterized and applied for adsorption of Acid dyes (Acid Blue 62 (AB62) and Acid Red 266 (AR266)) from aqueous Medias. Adsorption of AB62 and AR266 on SBA-15 ordered mesoporous silica, polyamidoamine functionalized SBA-15(SBA-15-PAMAM), has been investigated. In order to assess the synthesized adsorbent constructional, FT...
