| 摘 要： | This article studies the interactions of trace-elements in seawater with clay minerals and presents a chemical model-the main action of cation exchange in lower concentration of Pb and the main action of surface precipitation in higher concentration of Pb. Two actions are proved by the pH effect and the temperature effect of the interaction respectively. Applying Toth equation describing gas-solid adsorption to our experimental systems, we have established the isothermal formulae for liquid-solid systems. The theory curves agree with the measuring results.
