The pollution of surface and ground water by heavy metals is a major problem for the environmeat; therefore, it is necessary to eliminate these toxic substances. There are many methods to remove these pollutants, such as adsorption, chemical precipitation, and membrane filtration. In our study, zinc is adsorbed on peapods and ivy leaves. Contact time is 30 min for the two adsorbents, and optimal pH is 4 for ivy leaves and 5 for peapods. Results indicate that adsorption isotherms were of type I.
