ith coolants. In nuclear power plants, these oxides trap radioactive ions, leading to buildups of radioactivity that require costly cleanups of reactor surfaces. Cobalt, present in some alloys used in the reactors' water systems, is a major contributor toward this problem because of its long half-life.
In the study, the researchers created an adsorbent material that unlike conventional ion-exchange resins that are frequently used in reactors is selective for cobalt but has the unique ability of disregarding iron-based ions. The polymer's high selectivity increases its appeal, the researchers add, for use in decontamination processes in reactors that utilize a variety of structural materials. JS

New EU regulations force cosmetics firms to abandon safety tests in animals
Chemical & Engineering News
New European Union (EU) regulations restricting use of animals to test the safety of shampoo, nail polish, and other personal care products are forcing cosmetic makers to seek alternative ways to test these products, according to an article scheduled for the May 11 issue of Chemical & Engineering News, ACS' weekly newsmagazine.
C&EN senior correspondent Marc Reisch explains in the cover story that an EU regulation now restricts use of animal testing, and will totally ba
