Abstract

In the Present work the enicostemma littoraleare used as adsorbent for removal of heavy metals like Fe(III), Cu(II), Cr(II) from aqueous solution. The adsorption characteristics of all three metals on enicostemma littorale was evaluated as a function of varying adsorbent dose, tempera ture and time. The percentage removal of Fe(III), Cu(II), Cr(II) bytitanium oxide enicostemma littorale carried under different conditions, during this findings was significant. The order of adsorption ontitanium oxide enicostemma littorale of metals ions were Cu >Fe>Cr during the findings. The adsorption data fitted well into Freundlich and Langmuir adsorption models. The results show that titanium oxide enicostemma littorale hold a great potential in removal of metal ions from aqueous solution. The Thermodynamic study has showed that the Fe(III), Cu(II), Cr(II) ions adsorption on the surface of titanium oxide enicostemma littorale was physical adsorption and the process was spontaneous and exothermic.
