The aim of this research was to assess the efficiency of Fenton’s oxidation for degradation of endocrine disruptor bisphenol A (BPA) with emphasis on extent of accompanying adsorption. Adsorption on the waste sludge resulting from the Fenton’s oxidation could represent a significant impact on the final removal efficiency of BPA. Fenton’s oxidation was accomplished at two concentrations of BPA (...

CMK-8, a mesoporous carbon material, was activated using different methods for the adsorption of low-concentration airborne formaldehyde. KOH and ammonia treatments were used to activate CMK-8. A CMK-8 sample was treated with KOH first followed by an ammonia-treatment at 700 degrees C to determine the effect of a combination of the two treatment methods. The adsorbents prepared were characteriz...

The synthesis and characterization of BiOCl and Fe3+-grafted BiOCl (Fe/BiOCl) is reported that are developed as efficient adsorbents for the removal of cationic dyes rhodamine B (RhB) and methylene blue (MB) as well as anionic dyes methyl orange (MO) and acid orange (AO) from aqueous solutions with low concentration of 0.01~0.04 mmol/L. Characterizations by various techniques indicate that Fe3+...

Introduction: Discharge of textile wastewater causes the reduction of sunlight penetration, interferes with the receiving waters ecology and damage the environment. The aim of this study was to determine the removal efficiency of reactive blue 19 dye from aqueous solutions by cuttlefish bone powder. Materials & Methods: This study was performed experimentally and in laboratory scale. In thi...

Reactive blue dye was evaluated as a corrosion inhibitor for zinc in 0.5N HCl by weight loss, gasometric and thermometric methods. The inhibition efficiency was found to increase with increase in the inhibitor concentration. The adsorption of the inhibitor molecules on the zinc metal surface obeyed Temkin adsorption isotherm.

background chromium is one of the most commonly used heavy metals in industry. it is known as a pollutant that its discharge into the environment needs special care. objectives the current study aimed to evaluate the functionalized multi-walled carbon nanotubes (f-mwcnts) as a novel adsorbent of chromium in aqueous solutions. materials and methods the virgin mwcnt was protonated using sulfuric ...

Background & objectives: Dyes are structurally complex materials, which enter into the environment due to discharging of textiles effluent from dyeing and printing processes. Reactive Blue 52 dye is used widely in the textile industry. Therefore, we investigated the efficiency of the filamentous Alga as natural adsorbent in the removal of Reactive Blue 52 dye from textile wastewater. Methods: ...

The inhibitive effect of congo red was examined as corrosion inhibitor for the corrosion of zinc in 1N HCl by conventional weight loss and gasometric methods. Results obtained show that congo red exhibited high inhibition efficiencies. The inhibition efficiency was found to increase with increase in the inhibitor concentration. The adsorption of the inhibitor molecules on the zinc metal surface...

The inhibitive effect of a few thiols were examined as corrosion inhibitors for the corrosion of zinc in 1N HCl and 1N H2SO4 by conventional weight loss and gasometric methods. Results obtained show that all the thiols exhibited high inhibition efficiencies. The inhibition efficiency was found to increase with increase in the inhibitor concentration. The adsorption of the inhibitors obeyed Temk...
