Isotherm, kinetic and thermodynamic as well as biosorption mechanism were investigated and discussed. Dye uptake increased with increase in initial dye concentration but decreased with increase in time. Maximum biosorpion capacity and optimum temperature were 161 mg/g and 45 °C respectively. Liquid film diffusion controlled the process which was endothermic, spontaneous and physisorptive. Egg membrane appears to be a novel natural membrane for removing cationic substances from aqueous solutions. It is environmentally friendly.  %U https://www.ajgreenchem.com/article_81741_2f44b6baaddfa0a2da59913203671ffc.pdf
