Abstract:
Environmental pollution as a result of the dye presence led to serious health problems. In this study, the adsorption by weld seeds were investigated. The adsorption behavior of weld seeds with Methylene Blue dye has been studies by batch method to consider its application in this field The effects of various experimental parameters like contact time, dosage of weld seeds, initial concentration of the Methylene Blue, pH and temperature have been investigated. The removal percentage is a pH dependent and decrease with increase in temperature, the best removal were at 293K. The adsorption kinetic data are best described by pseudo- second-order kinetic model with good correlation coefficient. The experimental results indicate that freundlich isotherm describes the biosorption of methylene blue onto the weld seeds better than others at all the temperature studied. The calculated thermodynamic parameters (ΔG°, ΔH° and ΔS°) show that its adsorption is spontaneous and exothermic in nature.
