Removal of hexavalent chromium using coffee husk
The potential to remove chromium(VI) from aqueous solutions through biosorption using coffee husk was investigated. The effects of pH, contact time, initial concentration and adsorbent dosage on the adsorption of Cr(VI) were studied. The data obeyed Langmuir and Freundlich adsorption isotherms. The Langmuir adsorption capacity was found to be 44.95 mg/g. The Freundlich constants Kf and n were 1...
متن کاملApplication of modified bentonite using sulfuric acid for the removal of hexavalent chromium from aqueous solutions
Background: Environmental contamination by chromium (Cr) has become an important issue due to its adverse effects on human health and environment. This study was done to evaluate the application of modified bentonite using sulfuric acid as an adsorbent in the removal of hexavalent Cr from aqueous solution. Methods: Adsorbent features were determined using x-ray diffraction (XRD), fourier transf...
متن کاملRemoval of Hexavalent Chromium Ions from Aqueous Solution by Adsorption Using Activated Carbon Prepared from Cucumis Melo Peel Activated carbon
Activated carbon prepared from Cucumis Melo Peel was used as adsorbent for the removal of chromium ion from aqueous solution. Adsorption experiments were performed by varying initial metal ion concentration, temperature, and pH. Freundlich and Langmuir isotherms were used to analyze the equilibrium data obtained at different adsorption conditions. Adsorption results obtained, shows that the Cr ...
متن کاملRemoval of hexavalent chromium from aqueous solution using canola biomass: Isotherms and kinetics studies
The removing of hexavalent chromium from wastewater or decreasing its chromium (VI) content up to the permitted levels is important due to its non-biodegradation, bioaccumulation, and cancer-causing and toxic effects. In the present study, biosorption of Cr (VI) from aqueous solutions using canola was investigated. The various physicochemical parameters such as pH, initial Cr (VI) ion concentra...
متن کاملStudies on heavy metal removal efficiency and antibacterial activity of chitosan prepared from shrimp shell waste
Chitosan, a natural biopolymer composed of a linear polysaccharide of α (1-4)-linked 2-amino 2-deoxy β-D glucopyranose was synthesized by deacetylation of chitin, which is one of the major structural elements, that forms the exoskeleton of crustacean shrimps. The present study was undertaken to prepare chitosan from shrimp shell waste. The physiochemical properties like degree of deacetylation ...
