文摘
- •
Polymers like LDPE are often used in passive samplers for monitoring chemicals in water.
- •
A requirement for using these samplers is knowledge of the polymer–water partition coefficient.
- •
Directly measuring polymer–water partition coefficients can be experimentally difficult.
- •
A new way is described that relies on polymer–micelle and micelle–water partitioning.
