The Study Of Application About Sepiolite Using As Adsorbent In The Wastewater Treatment

Sepiolite is a fibrous silicate clay mineral with excellent absorbability , Theological behavior and catalytic activity etc owing to its high specific surface and unique porous structure. 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 (Ag+), dynamite cotnposton in water (TNT) 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.
