Application of adsorbent from Dum palm for the removal of Manganese (II), Zinc (II) and Copper (II) ions from aqueous solution
نویسنده
چکیده
The batch adsorption of Mn (II), Zn (II) and Cu (II) ions from aqueous solution using frond and leaves of dump palm was investigated. The influence of sorption time, initial metal ion concentration and adsorbent dosage were evaluated. The results showed that these parts of dump palm have relatively high adsorption capacity for these heavy metals ions. The percentage removed was (76%), (64%), (62%) and (64%) (57%) (56%) for Mn (II), Cu (II) and Zn (II) ions respectively for frond and leaves. Adsorption equilibrium was established in 90mins for Mn (II), Cu (II) and Zn (II) ions. The equilibrium data generated fitted well for Freundlich adsorption model. The obtained results show that the both the leaves and the frond of dump palm are favourable for the sorption of the heavy metal ions.

Presence of heavy metal ions in wastewater is an important public concern. Adsorption are commonly used technique to remove various pollutants, including the ions, from contaminated water sources. However, common methods for adsorption are not completely efficient at low ion concentrations and the adsorbent should be improved in order to reaching the acceptable levels of adsorption efficiency. ...
