Heavy metals contamination has become a global issue of concern due to their higher
toxicities, nature of non-biodegradability, high capabilities in bioaccumulation in human …

An analytical approach for estimation of the thermodynamic parameters from the Langmuir
isotherm constant has been introduced in the present paper. The concept of the …

Biosorption was carried out in this study using the biomass of microalgae Scenedesmus sp.
as adsorbent for the removal of hexavalent chromium or Cr (VI) from solution. Different …

Adsorption is a promising clean water technology process. Many materials both inorganic
(such as zeolite, clays) and organic (such as residues from agricultural industry) have been …

Water contamination is an environmental burden for the next generations, calling for
advanced methods such as adsorption to remove pollutants. For instance, unwanted …

An alginate gel bead composite adsorbent with polyethyleneimine (PEI) as a surface
modifier and Eichhornia crassipes (EC) biochar, known as EC-alg/PEI-3, was added …

Heavy metals from industrial effluent are major threat to environment because of their major
toxicity effect. The treatment of metal contaminated wastewater is of special concern. This …

In this study, Rosa damascena leaf powder was evaluated as a biosorbent for the removal of
copper from aqueous solutions. Process variables such as the biosorbent dose, pH, and …

In last decades, the biosorption process has become one of the main alternative treatment
technologies for the removal of pollutants from dilute aqueous solution. Among these …

During the past years, the ecological integrity and biodiversity of marine ecosystems have
been highly threatened due to the controlled or uncontrolled release of high concentrations …
