Background and purpose: Recently, release of pollutants such as heavy metal ions to the environment becomes one of the most important problems for soil and water. The present study was conducted to introduce modified rice husk (RH) as a new low-cost adsorbent. Materials and Methods: In this study, tartaric acid modified RH (TARH), was used as an adsorbent for removal of Ni(II) and Cd(II) from w...

Adsorption of zinc (Zn), cadmium (Cd), and nickel (Ni) from aqueous solutions by corncob (CC) granular activated carbon prepared (GACC) were carried out. Synthetic Cd, Ni, Zn at 3.0 ppm each used to perform the adsorption process. A batch pattern was determine kinetics as well isotherm parameters. The obtained results using either both CC GACC separately found be matched with Langmuir model. Fu...

The effective removal of heavy metals from industrial wastewater is the most important issues for many industrialized countries and it is big challenge for human being. This research focuses on understanding adsorption process and developing a cost effective technology for treatment of heavy metals-contaminated industrial wastewater. In this investigation the Fe2O3 magneti...

Jute modified has been used for adsorption of Cr (VI), Cd (II) and Pb (II) ions over a range ofinitial metal ion concentration. Adsorption process is done in batch mode. Adsorption isotherms ofthe heavy metals on adsorbents prepared were determined and correlated with common isothermequations. It was found that the Freundlich isotherm is better than Langmuir for explaining thebehavior of adsorp...

This work deals with geopolymers based on local Jordanian resources, namely, kaolin and zeoltitic (phillipsite) tuff. The geopolymers were prepared from these two materials by a reaction with an alkali solution at 80oC. The research group of the present work has demonstrated in previous work that addition of zeolitic tuff to kaolin based-geopolymers increases the adsorption capacity toward Cu(I...

The effects of repulsive interaction on the electric double layer (EDL) and differential capacitance (Cd) of an ionic liquid (IL) 1-butyl-3-methyl-imidazolium hexafluorophosphate (BMIM(+)/PF6(-)) on the graphite electrode were studied by molecular dynamics (MD) simulations. The strength of repulsive interaction was studied by manually tuning the parameter lambda (λ) with λ = 1.00 for normal Len...

Introduction: Electrospun nanomembranes have been used for effective air filtration due to their potential for active surface modification. This study aims to synthesize polyurethane (PU) nanofiber membrane incorporated with different amounts of β-cyclodextrin (β-CD) to capture volatile organic compounds (VOCs) along with aerosol filtration from the air. Material and Methods: First, PU was sy...
