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.

In 2000, Nishida et al synthesized the PPDO whose molecular weight could reach 142,000 but the monomer conversion could only reach 79.4% by using stannous octoate as catalyst with co-initiator under conditions that T = 100oC, M/I = 4900, t = 20 h, in 2000, the enzymatic polymerization of PDO was carried out at 100oC for 15 hours using 5wt% immobilized lipase CA by Nishida et al.
这主要是因为PDO的结构相对稳定,开环聚合要比GA、LA、CL困难一些,而且用于PDO开环聚合的催化剂体系单一,主要集中在Ti, Zr, Sn, Ld, La, Yb, Hg等重金属,然而这些重金属作为副产物,不容易从PPDO中分离出来,阻碍了PPDO作为医用材料的应用,这也造成了PPDO的成本昂贵。
