Removal of Fe and Cu Ions from Aqueous Solutions by Adsorption Using Peanut Hulls
نویسنده
چکیده
The present study was conducted to evaluate the possibility of using peanut hulls for the removal of Feand Cu from aqueous solutions.This paper incorporates the effects of dose, concentration and pH.Adsorption of heavy metal on adsorbents was found to increase on decreasing initial concentration, the sorption capacity strongly increased with pH in the range 3-4. The results showed that the removal of heavy metals, such as Feand Cufrom aqueous solution was efficient using peanut hulls as bioadsorbent. The adsorption percentage of Feand Cu ions by peanut hulls were very high. The Langmuir isotherm model was the best to describe the experimental data. The maximum sorption capacity was found to be 79.28 and 96.58 mg/g for Fe and Cu, respectively. Over all, the present findings suggest that peanut hulls are friendly environmental bioadsorbent, efficient and low cost biosorbent which represents an excellent potential for Fe +3 and Cu removals from aqueous solutions.
