高岭土对钙离子的吸附特性研究

In this study, the adsorption properties of calcium ions on kaolin under the influences of adsorption time, temperature, calcium ions concentration, adsorbent concentration, and surging intensity were studied by static experiments. The result indicates that the adsorption process was departed into two stages , rapid and slow adsorptions, and the adsorption equilibrium time was shortened with the temperature rising; the optimum temperature of this process was around 20 oC；the adsorption equilibrium capacity was reduced with the concentration of adsorbent rising, until up to an equilibrium; in the experimental context, the adsorption equilibrium capacity increases with the Rotate-speed rising.
