摘要：

The sorption of lead by three soils that differed in texture and calcium carbonate content was studied at three different temperatures. Lead sorption was found to conform to both Freundlich and Langmuir isotherms. Soil adsorption maxima were derived from the reciprocal of the slope obtained by a least-squares fit of Langmuir plots for each soil. The highest adsorption capacity was exhibited by CaCO3-rich soil (773.55 mmol Pb kg-1). Raising the temperature from 298 K to 308 and 318 K increased the sorption capacity of all of the soils.
