Adsorption and desorption phenomena of polycyclic aromatic hydrocarbons (PAH) on coal fly-ash. Periodic report for the period from
January 1989 to June 1989
report
Upon finding that the CO2 pump was a source of oil (mentioned MT-TNO report R 89/074) the oil was replaced by a water/glycerol mixture in anticipation of another pump. This new pump, one with a stainless steel membrane, was ordered immediately but due to the long delivery time experiments had to start with the old pump. Test runs gave extracts containing some water, indicating diffusion through the teflon pump-membrane. Three fly-ashes have been extracted, the results indicate a high extraction capacity.
