Studies on Adsorption of Organo-Mineral ions using Eucommia ulmoides Leaves

The removal of organo-mineral ions from synthetic water contaning heavy metals and pesticides using Eucommia ulmoides leaves were studied varying time, timperature, 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 Zn. As the heavy metals concentration increased, the removal efficiency of adsorbent was not invariable ratio and pesticide in 2.0 mg/l(parathion, diazinon, malathion) was maximum adsorbted respectively 91.3%, 88.2%, 59.2%. The removal efficiency according to varying pH was maximum adsorpted in pH 7. The injected adsorbent in which 2.0 g was maxium adsorpted and the removal of Pb was found to have the best removal efficiency.
