Uranium Gathering Plastic Preparation
September 25, 2012 | Leave a Comment
Polyethylene fiber is given a chemical structure of high affinity to uranium in seawater by radiation-induced graft polymerization. Adsorbent is formed into a lace by twisting the resulting polyethylene fibers. The braided adsorbent can be lifted from the sea bottom and moored, since floats are incorporated in it. The braid type adsorbent was pulled up after soaking in seawater for 60 days. The adsorbed uranium on the adsorbent was collected by elution with acid solution.
