Application of modified bentonite using sulfuric acid for the removal of hexavalent chromium from aqueous solutions

Background: Environmental contamination by chromium (Cr) has become an important issue due to its adverse effects on human health and environment. This study was done to evaluate the application of modified bentonite using sulfuric acid as an adsorbent in the removal of hexavalent Cr from aqueous solution. Methods: Adsorbent features were determined using x-ray diffraction (XRD), fourier transf...

Removal of phenol from aqueous solutions using persulfate-assisted, photocatalytic-activated aluminum oxide nanoparticles

The combination process of UV/ S2O82-/Al2O3 leads to the production of radicals and radical hydroxyls, which could decompose and remove various pollutants, such as phenol. The present study aimed to investigate the photocatalytic efficiency of aluminum oxide nanoparticles and persulfate compilative processes in the removal of phenol. This e...

Kinetic study of heavy metal ions removal from aqueous solutions using activated pumice stone

Background: The presence of heavy metals in aquatic and terrestrial ecosystems causes harmful effects to living organisms in the environment. This research aimed to determine the potential of activated pumice stone (APS) as a sorbent for the removal of Cd, Cu, and Zn from wastewater. Methods: This research was conducted during 2013 on a laboratory scale. The study was performed using batch exp...

Photocatalytic Removal of Malachite Green Dye from Aqueous Solutions Using Halloysite–TiO2 Nanocomposite

 Background and purpose: Malachite green is one of the most widely used dyes in various industries, aquaculture, and fungicides. The residues have adverse effects on environmental and human health and should be removed from the effluent before discharging to the environment. The purpose of this study was to investigate the efficiency of photocatalytic process using halloysite-titanium dioxide n...
