Abstract :

In this paper removal of methylene blue dye from wastewater was studied. Separation was studied by adsorption batch method. Adsorbent is tassel that is an agricultural waste. The effect of temperature, time, pH and solution volume on adsorption was investigated. This adsorbent was eluted and treated by Ethylenediamine 1M for 60 min. The best fitted isotherm model was Langmuir and maximum capacity was obtained 166 mg dye on 1g adsorbent. The best kinetic model was pseudo second order model.
