A Study on Adsorption of Organo-mineral Ions Utilizing Eucommia Ulmoides Leaves
Choi Han-Young

Abstract
The removal of organo-mineral ions from synthetic water contaning heavy metals and pesticides using Eucommia ulmoides leaves were studied varying time, temperature concentration, pH and adsorbent amount. The removal rate of organo-mineral ions according to varying time were invariable detected only Cr and parathion and its was adsorption removal rate respectively 95%, 86.4%. The removal efficiency of organo-mineral ions according to varying temperature was decreased only Zinc. As the heavy metals concentration increased, the removal efficiency of adsorbent was not invariable ratio and pesticide in 2.0mg/l(Parathion, Diazinon, Malathion) was maxium adsorbented respectively 91.3%, 88.2%, 59.2%. The removal efficiency according to varing pH was maximum adsorpted in pH7. The injected adsorbent in which 2.0g was maximum adsorpted and the removal of Pb was found to have the best removal efficiency.
