Methylene blue dye (MB dye) is a harmful contaminant for wastewater streams of industries and to human aquatic life. An ecofriendly sugar templating process was used generate porous bentonite/polydimethylsiloxane (PB) magnetite nanoparticles/bentonite/polydimethylsiloxane (PBNP) composite absorbents remove MB in this study. During the infiltration PDMS solution into template vacuum chamber, ben...

We utilize isotherm models in contributing to scholarly knowledge in simple terms, to measure the forces or energy defining certain adsorption phenomenon. Gas Chromatography coupled with Mass Spectrophotometer detector (GCMS) was utilized to measure equilibrium phase atrazine after adsorption onto Shea nut Shells (SS) acid derived activated carbon. Data were fitted into the D-R and Temkin i...

Zeolites are widely used in wastewater and contaminated water refinement due to their great adsorption properties. However, Clinoptilolite (as one type of Zeolites) has a relatively low adsorption capacity at least for arsenic ions. Therefore, in order to increase the adsorption capacity, natural Clinoptilolite was modified with sulfuric acid and various tests were then conducted to determine t...

In this study, two Carbon Molecular Sieves using Pistachio shell (CMS P) and Walnut shell (CMS W) were prepared by a chemical vapor deposition method and used for pressure swing adsorption and separation of CO/H2 and CO/CH4. Adsorption isotherms of gases obtained for both CMS’s. The Dubinin-Radushkevich isotherm model was used for comparing pore volum...

The present study focuses on the synthesis of Kaolin loaded Silver (Ag-KNC) and Nickel (Ni-KNC) nanocomposites by co-precipitation method. The surface morphology of them was determined by SEM technique while chemical composition was determined by FT-IR technique. The removal of Malachite Green Oxalate (MGO) was preceded by the adsorption method using (Ag-KNC) and (Ni-KNC). The adsorption mo...

The present study was carried out to investigate the adsorption and leaching behavior of Cu2+, Zn2+ and Pb2+ by sediments collected from the western banks of three different sectors along River Nile at Aswan governorate, Egypt. The feasibility of sediments for the removal of Cu2+, Zn2+ and Pb2+ from aqueous solutions was tested under the effect of three conditions (pH, initial metal concentrati...

Background: The efficacy of NH4Cl-induced activated carbon (NAC) was examined in order to adsorb RR198, an azo reactive model dye, from an aqueous solution. Methods: The effects of pH (3 to 10), adsorbent dose (0.1 to 1.2 g/L), dye concentration and contact time on the adsorption efficiency were investigated. Results: The results showed that the removal of dye was highest at a solution pH of ...

Herein, mesoporous magnetic nanocomposite (Fe3O4@SBTCA) was specifically designed and fabricated for its high efficient application in the removal of toxic Cd(II) ions from aquatic environment. The structure, surface characteristics, composition nanocomposites were characterized by FT-IR, BET analysis, XRD, TEM, EDX, Zeta potential measurement TGA analysis. TEM images XRD exhibited average part...

Natural dyes exhibit a low dye uptake when cellulosic fiber dyeing is carried out using conventional water bath process. In this research, cotton fabric was exhaust dyed in microemulsion dyebath containing cacao husk extracts and decamethylcyclopentasiloxane (D5) to achieve higher exhaustion percentage on fiber, which an environmentally beneficial The adsorption behavior of extract D5 system in...

In this work the feasibility of employing calcareous soil to remove lead (II) ions from its aqueous solutions was investigated under batch mode. The influence of solution pH, sorbent dose, initial lead (II) concentration, contact time, stirring rate and temperature on the removal process were investigated. The lead adsorption was favored with maximum adsorption at pH 6.0. Sorption equilibrium t...
