[ 1 ] - Removal of Dimethyl Phthalate from Aqueous Solution by Synthetic Modified Nano Zeolite Using Cu2O Nanoparticles
In this paper, a novel nano crystalline sodalite was synthesized and characterized by XRF, XRD, SEM and FTIR analysis. Cu2O nanoparticles (30-60 nm) were loaded on nano zeolite bed and utilized as an adsorbent to remove dimethyl phthalate. The SEM-EDX of modified zeolite indicates that the amount of copper loading on the zeolite was 4.5 wt%. Modified nano zeolite was used as an effective adsorb...
[ 2 ] - Removal of Strontium Ions by Synthetic Nano Sodalite Zeolite from Aqueous Solution
In this research, the zeolite sodalite, as an inorganic ion exchange material, was chemically produced in the template-free synthesis and evaluated in order to facilitate the sorption of strontium ions from aqueous solutions in batch operations onto acid treated zeolite with dilute H2SO4 solutions. The following indicates what the batch experiments included: a sorbent amount of 0.25 g in 100 mL...
[ 3 ] - Removal of Diazinon from Aqueous Solutions in Batch Systems Using Cu-modified Sodalite zeolite: An Application of Response Surface Methodology
In this work, perlite was used as a low-cost source of Si and Al in the synthesis of sodalite zeolite using hydrothermal synthesis method. Cu2O nanoparticles were coated on a bed of sodalite zeolite and used as an adsorbent for removal of diazinon from aqueous solutions. To analyze the process, a significant variable .i.e. removal efficiency (%) of diazinon and three dependent parameters as the...
[ 4 ] - Modeling and Comparison of Optimized Isotherm Models for H2, N2, CO, CH4 and CO2 Adsorption Using Cuckoo Search Optimization Algorithm
In this study, modeling of hydrogen, nitrogen, carbon monoxide, methane and carbon dioxide sorption on UTSA-16 framework extrudates in the pressure swing adsorption process was carried out. The pure gas adsorption of these gases at the pressure range (0 to 80) bars at (298, 313, and 338) K have also been measured in a fixed bed. Langmuir, Toth, Sips, UNILAN, Virial and Dubinin-Astakhov adsorpti...
