摘要 |
<p>Methods for extracting bisphenols from polymer substrates are described. The methods include contacting the polymer substrate with an aqueous composition which includes a phase transfer agent, a base and optionally an oxidant, whereby the bisphenol is extracted into the aqueous composition. Suitable phase transfer agents are delineated. Also described are compositions which can be used in the present methods.</p> |
