First, we investigate the methods of sepiolite s purification from ore , from which we get the incompact short fibrous sepiolite for the experiment ; the prime activatited term is also obtained through this experiment. We use activated sepiolite to process the absorption experiment on heavy meatal ion ( Ni2+, Cr6+, Pb2+, Cu2+, Cd2+), noble metal ion, dynamite cotnposton in water and industrial oil. we take Ni2+ for example to confirm the prime adsorbent term , from the experiment we get the adsorbent isotherm . Make the dynamic absorption experiment and regenerate experiment using sepiolite on the heavy metal(Ni2+) on the base of static absorption experiment.
