Investigation of Methylene Blue Dye Adsorption from Polluted Water Using Oleander Plant (Al Defla) Tissues as Sorbent

The main purpose of this research was to investigate the ability of Oleander plant (Al Defla) tissues to adsorb Methylene Blue (MB) dye from polluted water. The experiments were carried out through batch-adsorption technique to investigate the influence of the following experimental parameters on adsorption process namely, adsorbent quantity, MB initial concentration, adsorbent particles size, ionic strength, pH and temperature. The observation indicated an ability of the plant tissues to adsorb MB from water. Adsorption of Methylene Blue was increased on increasing the temperature, pH, adsorbent amount and the initial dye concentration factors. While it decreases with increase of salt concentration and increase of the adsorbent particles size. Plant fruit clusters are more likely to adsorb MB dye from water than leaves. Langmuir and Freundlich isotherms were used to model the adsorption data, which was fitted with these models. The isotherms parameters indicated that the adsorption was monolayer physical process.
