## Abstract Polymer additives were extracted from polyethylene with supercritical carbon dioxide. The twoโfilm theory, which considers mass transfer across a phase boundary, is applied to qualitatively describe the kinetics of mass transfer from the core of the polymer particles into the supercriti

## Abstract An automated supercritical fluid extraction system was evaluated with polynuclear aromatic hydrocarbons and phenols to demonstrate extraction efficiency, collection efficiency, and sample cross contamination. Results showed that 75/25 glass beads/octadecyl silica provided the highest co
