in the present study we search potential of pt-decorated graphene (ptg) as a new nanostructure adsorbent for nitrous oxide (n2o) using density functional theory (dft). after fully relaxation of different possible orientations of n2o-ptg complex, we distinguished two optimized configurations for this system; 1- terminal n-side of gas is oriented towards pt so that the molecule axis is perpendicu...
The effect of sugarcane straw anion exchanger with Micro and Nanostructure scale as the adsorbent for contaminated water treatment was investigated. The effects of operating conditions such as adsorbent loading, initial anion concentration, pH and the presence of competitive ions on the adsorption performances were examined. Equilibrium time and pH and adsorbent dosage were 3h, 6 and 0.5g respe...
Recent efforts have been directed towards the design of efficient and contaminant selective remediation technology for the removal of perfluorinated compounds (PFCs) from soils, sediments, and aquatic environments. While there is a general consensus on adsorption-based processes as the most suitable methodology for the removal of PFCs from aquatic environments, challenges exist regarding the op...
This study focuses on the application of nanostructured Mg-Al layered double hydroxide as a promising adsorbent in desulfurization of dibenzothiophene, an aromatic sulfur bearing compound from gasoil model. The Mg-Al LDH was synthesized by a co-precipitation method and characterized by FT-IR, XRD, EDX and SEM. The XRD and FT-IR approved the layered structure and crystalline form of the adsorben...
Zinc hydroxide chloride nanostructure was successfully synthesized through a simple method at low temperature by sonochemical process. The morphology and crystalline of the products were analyzed by XRD, FESEM and TEM. The effect of independent variables including contact time, solution pH, adsorbent dosage and the concentration of dyes on response performance with response to surface methodolo...

Herein we report superior dye-adsorption performance for flower-like nanostructure composed of two dimensional (2D) MoS2 nanosheets by a facile hydrothermal method, more prominent adsorption of cationic dye compared with anodic dye indicates the dye adsorption performance strongly depends on surface charge of MoS2 nanosheets. The adsorption mechanism of dye is analyzed, the kinetic data of dye ...
