This study deals with the adsorption characteristics of heavy metal with Dangjin clay under batch type operation. The adsorption was maintained under various experimental conditions; the initial concentration of pb²⁺ and cd²⁺ solution, the adsorbent weight and the contact time and pH. This results was as follows; the adsorption of pb²⁺ and cd²⁺ to the adsorbent reached the equilibrium adsorption in approximately 30 minutes. When the initial concentration of solution was low, adsorbent weight was 0.5 g and at alkalnity pH range, adsorptivity of pb²⁺ and cd²⁺ was increased. The adsorption isotherm equation to pb²⁺ agreed with the Freundlich isotherm equation. The Freundlich constant l/n was 0.3905, which meant a good adsorbent for the remove of pb²⁺.
