We report on a facile and rapid microwave-assisted method for preparing a sodium-cadmium metal-organic framework (having coordinatively unsaturated sodium ions) that considerably shortens the conventional synthesis time from 5 days to 1 hour. The obtained (Na,Cd)-MOF showed an excellent volumetric CO2 adsorption capacity (5.2 mmol cm(-3) at 298 K and 1 bar) and better CO2 adsorption properties ...

Wet washing is a widely used method for biodiesel purification. However, this technique generates large amount of wastewater that needs to be treated afterward, which costly and time-consuming. Thus, solvent-aided crystallization (SAC) with ultrasonic irradiation as solution movement assistance was introduced. This based on the addition 1-butanol enhance purification via crystallization. During...

In this study, the oxidation of dye from colored wastewater by H2O2/ MWCNT’s multi walls carbon nano tubes solution assisted with UV radiation was investigated. Disperse Blue 56 DB 56 was used as a model dye. Adsorption behavior of DB56 from aqueous solution onto MWCNT’s was investigated under various conditions such as initial pH value, dye concentration, H2O2 and MWCNT’s dosage. Maximum adsor...

Chelating resins have been considered to be suitable materials for the recovery of heavy metals in water treatments. A chelating resin based on modified poly(styrene-alt-maleic anhydride) with Melamine was synthesized. This modified resin was further reacted with 1,2-diaminoethan in the presence of ultrasonic irradiation for the preparation of a tridimensional chelating resin on the nanoscale f...

The green biosynthesis of zinc oxide nanoparticles (GBS ZnO NPs) using Ziziphus jujuba leaves extract assisted by ultrasonic irradiation was reported in this research work. biosynthesized NPs were characterized different techniques and the results revealed synthesis hexagonal wurtzite crystal GBS nanoparticles; per XRD measurement, with average practice size 90 ± 10 nm; based on both SEM TEM im...
