Optimization of Copper and Zinc ions removal from aqueous solution by modified Nano-bentonite using Response surface methodology

Presence of heavy metal ions in wastewater is an important public concern. Adsorption are commonly used technique to remove various pollutants, including the ions, from contaminated water sources. However, common methods for adsorption are not completely efficient at low ion concentrations and the adsorbent should be improved in order to reaching the acceptable levels of adsorption efficiency. ...

Hydrothermal synthesis of surface-modified copper oxide-doped zinc oxide nanoparticles for degradation of acid black 1: Modeling and optimization by response surface methodology

Dyes are widely used in various industries most of them are not readily biodegradable and are consisted of number of toxic, mutagenic, and carcinogenic compounds. Therefore, it is essential to remove them from effluent before their discharge to the environment. The objective of this investigation was to synthesize copper oxide (CuO) doped zinc oxide (ZnO) nanoparticles under mild hydrothermal c...

Thermal stabilization of alumina modified by lanthanum

Transition alumina, with different La loadings, were synthesized from boehmite (AlOOH) hydrosols containing a PEO/PPO/PEO triblock copolymer (Pluronics P123) and lanthanum nitrate. After calcination at 500 °C, the xerogels prepared from these sols have large specific surface area ( 400 m/g) and very large porous volumes, increasing with the amount of La to reach 2.5 cm/g for La/(La + Al) = 0.03...
