摘要：

The extraction of alkali metal tetraphenylborates by polyurethane foam was investigated. The extractability sequences are K+ almost-equal-to Rb+ > Cs+ and K+ almost-equal-to Rb+ almost-equal-to Cs+ for polyether and polyester foams, respectively. The high extraction of K+ by polyether foam can be explained by the cation chelation mechanism.
