Bioadsorption of Cd (II) from Contaminated Water on Treated Sawdust: Adsorption Mechanism and Optimization

Removal of Cd(II) ions from contaminated water by a new modified magnetic chitosan nano composite

Magnetic chitosan nanocomposites are one of the more recent advanced groups of adsorbents used to remove contaminants from waste water. In this research, N- Nicotinyl-N', N"-bis (Hexamethylenyl) phosphoric triamide (HE) was used as an additive to form a new nanocomposite with the structure of chitosan / 5% Fe3O4 Nps/10% HE resulting in the highly efficient removal of Cd(II...

Adsorption of Ni(II) and Cd(II) from Aqueous Solutions Using Modified Rice Husk

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...

Biosorption of Cd(II) and Ni(II) Ions From Aqueous Solution by Raw and Pre-Treated Cystoseira Indica Algae

Capturing Cd(ii) and Pb(ii) from contaminated water sources by electro-deposition on hydrotalcite-like compounds.

Two different hydrotalcite-like compounds were prepared and used as substrates for the electrochemical removal of extremely toxic pollutant cations, such as Cd(ii) and Pb(ii), from aqueous solutions, and their subsequent recovery for further potential applications. By deposition on the hydrotalcite electrode, it was possible to remove 75% of Cd(ii) contained in a starting 5.2 mM solution of CdC...
