Use of hen feathers as potential adsorbent for the removal of a hazardous dye, Brilliant Blue FCF, from wastewater

摘要: Waste material, hen feather, a biosorbent, was successfully utilized in removing water-soluble hazardous triphenylmethane dye, Brilliant Blue FCF from wastewater. The paper incorporates effect of pH, temperature, amount adsorbent, contact time, concentration adsorbate, etc. adsorption data validates Langmuir and Freundlich isotherms on the basis these thermodynamic parameters like Gibb's free energy, change enthalpy entropy were calculated. Kinetics ongoing also monitored specific rate constants for involved process calculated at different temperatures. Kinetic measurements suggest first order kinetics found to be applicable via film diffusion entire range.
