Analysis of a Non-crosslinked, Water Soluble Anion Exchange Resin for the Possible Presence of Parts Per Billion Level of Bis (Chloromethyl) Ether

Abstract

No evidence was found for the presence of bis-chloromethyl ether (bis-CME) in the resin at the detection limit ∼10 ppb with use of the hollow fiber probe-mass spec-trometric technique. The kinetic data indicate that bis-CME hydrolyzes rapidly and, therefore, cannot exist in any extended period of time in the resin solution.
