Abstract:

The objective of this study was to determine adsorption isotherms for polynuclear aromatic (PNA) compounds in methanol and a mixture of 50 percent methanol 50 percent water. The adsorption isotherms are useful in understanding the behavior of PNA compounds in relation to the presence of a cosolvent and PNA physical/chemical characteristics. The results presented here are part of a broader study of assimilative capacities and loading rates being conducted at Utah State University.
