Removal of Bisphenol-A from Aqueous Solution Using Rice Husk Nanosilica: Adsorption Kinetics, Equilibrium and Thermodynamic Studies

Kinetics and Equilibrium Studies of the Removal of Blue Basic 41 and Methylene Blue from Aqueous Solution Using Rice Stems

Synthetic dyes are among the most common contaminants of the environment. Therefore, the aim of this study was investigation the removal of Basic Blue 41 (BB41) and Methylene Blue (MB) from industrial effluents by useing raw and modified rice stems. In this study raw and modified rice stems treated chemically with Citric Acid (CA) and were used to explore the potentiality of rice stems for ...

removal of arsenic from aqueous solution using silica ceramic: adsorption kinetics and equilibrium studies

the removal of as(iii) ions from aqueous solutions has been investigated using silica ceramic under different experimental conditions of initial arsenite concentration, adsorbent dose, temperature and ph. better removal was obtained at temperature 25âºc and ph 7.5. the adsorption data have been explained in terms of langmuir and freundlich equations. the sorption kinetics was tested for the pse...

Application of Copper Vanadate Nanoparticles for Removal of Methylene Blue from Aqueous Solution: Kinetics, Equilibrium, and Thermodynamic Studies

Copper vanadate nanoparticles were synthesized by a simple coprecipitation method in an aqueous medium and the products were used as adsorbents for eliminating methylene blue (MB) from water. The structure and morphology of the produced nanoparticles were evaluated through X-Ray Diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM) analysis. The results...

Adsorption of Malachite Green from Aqueous Solution by Nanozeolite Clinoptilolite: Equilibrium, Kinetic and Thermodynamic Studies

The object of present study was to examine the adsorption potential of nanozeolite clinoptilolite (CP) for the removal of malachite green (MG) from aqueous phase in a batch equilibrium system. SEM, EDX, XRF, XRD and FT-IR techniques of characterization of zeolite were applied. The effects of initial pH solution, adsorbent dose, temperature, contact time and initial MG concentration on adsorptio...

Removal of phenol from aqueous solution by adsorption onto seashells: equilibrium, kinetic and thermodynamic studies

The efficacy of seashells as a new adsorbent for removal of phenol from aqueous solutions was studied by performing batch equilibrium tests under different operating parameters such as solution pH, adsorbent dose, initial phenol concentration, and temperature. The phenol removal efficiency remained unaffected when the initial pH of the phenol solution was in the range of 3–8. The amount of phen...
