Evaluation of the Marine Algae Gracilaria salicornia and Sargassum sp. For the Biosorption of Cr (VI) from Aqueous Solutions

Evaluation of the Activated Carbon Prepared of Algae Marine Gracilaria for the Biosorption of Ni (II) from Aqueous Solutions

Biosorption of heavy metals can be an effective process for the removal and recovery of heavy metal ions from aqueous solutions. In this study, the batch removal of nickel (II) ions from aqueous solution under different experimental conditions using activated carbon prepared of red alga Gracilaria was investigated in this study. The nickel (II) uptake was dependent on initial pH and initial nic...

Cr(VI) ADSORPTION – MECHANISTIC APPROACH FOR BIOSORPTION FROM AQUEOUS SOLUTIONS

Removal of Hexavalent Chromium Using Activated Carbons Derived from Marine Algae Gracilaria and Sargassum Sp

Industrial wastewater contain higher quantities of salts besides chromium (VI) ions, therefore, the effect of these salts on the adsorption of chromium (VI) should be studied. In this research, the batch removal of toxic hexavalent chromium ions from wastewater and aqueous solution using two different activated carbon marine algae Gracilaria (red algae) and Sargassum sp. (brown algae) were exam...

Investigation of Cr(VI) Adsorption by Dried Brown Algae Sargassum sp. and Its Activated Carbon

In this research, the batch removal of toxic hexavalent chromium ions from wastewater and aqueous solution using dried (BD) Sargassum sp. (brown marine algae) and Activated Carbon (AC) prepared from it was examined. Biomass, pH and the initial concentration of Cr(VI), adsorption models and kinetic studies were investigated. The experiment was performed in a batch system and theeffe...
