Metal Extraction Capability for Hybrid Polymers Consisted of β-Cyclodextrin and Diatomite

抄録

Hybrid polymers consisted of β-cyclodextrin and diatomite were made in order to examine a metal extraction capability, where the weight mixture ratio of β-cyclodextrin and diatomite were changed from 1:0.5 to 1:5. It was recognized that polymer A obtained from mixing ratio of 1:1 shows highly extraction capability to platinum ion (Pt) with almost 80% extraction ability. On the other hand, polymer, which was made from mixing ratio of 1:5 of β-cyclodextrin and diatomite shows lower capability to Pt with 10%. Diatomite shows only 1.3% extraction ability to Pt, otherwise β-cyclodextrin polymer shows almost 20% extraction capability to Pt.
