Adsorption isotherms for the system n-heptane/ethanol/HDPE

The equilibrium isotherms for the adsorption of n-heptane and ethanol on high density polyethylene (HDPE) are reported at 27–110°C and at 20–100 mmHg. perimental apparatus and procedures are described for three methods, namely flow, static and chromatographic. tained results are discussed on the basis of the Henry law for adsorbates at low coverage on solids.
