Evaluating peats for their capacities to extract methyl tertiary butyl ether from contaminated water using solid-phase microextraction with gas chromatography.

Methyl tertiary butyl ether (MTBE), the most common fuel additive used to oxygenate gasoline, is being detected more frequently in drinking water supplies. This research investigates the capacities of 10 different types of highly characterized peats to extract MTBE from contaminated water. Peat samples were slurried for 24 hours under controlled conditions in aqueous solutions of MTBE.

Retention of nitrogen and phosphorous from liquid swine and poultry manures using highly characterized peats.

This paper reports on research designed to test the hypothesis that differences in peat composition will cause differences in amounts of N and P retained during contact with liquid swine manure (LSM) and liquid poultry manure (LPM). Peat types representing a wide range of properties were tested in order to establish which chemical and physical properties might be most indicative of their capacities to retain N and P from LSM and LPM. Eight-percent slurries (peat/LSM and peat/LPM) were measured for total nitrogen (TKN) and total phosphorous (TP) after 6, 24 and 96 hours.
