Removal of Copper (II) from Aqueous Solutions Using Cuttlebone as Bio-adsorbent

Using Generation 3 Polyamidoamine Dendrimer as Adsorbent for the Removal of Pentavalent Arsenic from Aqueous Solutions

Introduction: Arsenic is known as a carcinogenic compound in drinking water. It can cause acute and chronic effects on human health. In this study, the effect of polyamidoamine dendrimer generation 3 (PAMAM G3) as adsorbents for removal of arsenic (V) from aqueous solutions was evaluated. Materials and Methods: Adsorption experiment was studied in batch system and the effect of different varia...

Nanocrystalline Akaganeite as Adsorbent for Surfactant Removal from Aqueous Solutions

The present study presents the effective use of nanocrystalline akaganeite for the adsorption of an anionic (SDS), a cationic (CTAB), and a nonionic (tween80) surfactant from wastewater. Equilibrium experiments, as well as thermodynamic analysis, were performed. The maximum SDS adsorption occurs at the lowest pH value (5), the opposite is observed for CTAB (pH = 11), while for tween80, the chan...

Removal of perilous dyes from aqueous solutions with CuO adsorbent

An Economic Removal of Ni(II) from Aqueous Solutions Using an Indige- nous Adsorbent

Carbon slurry, dried in open air, has been used as an adsorbent material for the removal of nickel(II) from aqueous solutions at different experimental conditions in batch adsorption technique. The time required to attain equilibrium was found to be 50 minutes. The effects of initial concentration of Ni(II), particle size of adsorbent, adsorbent dose, temperature and pH on removal of nickel(II)...

Efficiency in phenol removal from aqueous solutions of pomegranate peel ash as a natural adsorbent

Background: Phenol is an organic pollutant found in industrial effluents that is very toxic to humans and the environment. This study used pomegranate peel ash as a natural absorbent to remove phenol from aqueous solutions. Methods: In this study, pomegranate peel ash in different doses was used as a new adsorbent for the removal of phenol. The effects of contact time, pH, adsorbent dose and i...
