Batch Study on COD and Ammonia Nitrogen Removal Using Granular Activated Carbon and Cockle Shells
Landfills generate leachate that contains elevated concentration of contaminants and is hazardous to human health and the ecosystem. In this study, the mixture of granular activated carbon and cockle shells was investigated for remediation of COD and ammonia from stabilized landfill leachate. All adsorbent media were sieved to a particle size between 2.00 and 3.35 mm. The optimum mixing ratio, ...
متن کاملApplication of Iron Impregnated Activated Carbon for Removal of Arsenic from Water
The presence of arsenic in drinking water is one of the greatest threats to public health. The aim of this experimental investigation was to study the removal efficiency of As(v) from water by application of iron-impregnated activated carbon(Fe-AC). Coating of activated carbon with iron salt was carried out by impregnation method and thermochemical reactions with using of 100 mM FeCl3 solution....
متن کاملArsenic removal by iron-modified activated carbon.
Iron-impregnated activated carbons have been found to be very effective in arsenic removal. Oxyanionic arsenic species such as arsenate and arsenite adsorb at the iron oxyhydroxide surface by forming complexes with the surface sites. Our goal has been to load as much iron within the carbon pores as possible while also rendering as much of the iron to be available for sorbing arsenic. Surface ox...
متن کاملThe Antibacterial Activity of Activated Carbon, Silver, Silver Impregnated Activated Carbon and Silica Sand Nanoparticles against Pathogenic E. coli BL21
One of the most widely used nanoparticles for water purification is activated carbon due to its large surface area and high adsorption capacity (Ortiz-Ibarra, et al., 2007). Activated carbon has proven to remove bacteria like Pseudomonas aeruginosa and Escherichia coli from fresh and potable water systems (Percival and Walker, 1999; Quinlivan, et al., 2005). Despite electrostatic repulsion betw...
متن کاملAcid Dyes Removal from textile wastewater using waste cotton activated carbon: Kinetic, isotherm, and thermodynamic studies
The present study aims at investigating the potential of activated carbon AC prepared from waste cotton fiber for the removal of Acid Dyes from aqueous solutions. The prepared activated carbon was characterized by pore structure analysis, Fourier transforms infrared spectroscopy FTIR. Batch adsorption studies were carried out and the effect of experimental parameters such as pH, initial dye con...
