A method and device for measuring release rates of contaminants in at least one of a fast release mode and a slow release mode in which a volatile liquid sample is introduced into a sealed transparent reactor vessel having at least one sorbent contained within the transparent reactor vessel and a separator for preventing direct contact between the at least one adsorbent and the at least one volatile liquid sample in the transparent reactor vessel, whereby substantially zero headspace is maintained within the transparent reactor vessel. At least one solvent soluble constituent present in the at least one volatile liquid sample is passed through the separator, resulting in sorption of the at least one solvent soluble constituent by the at least one sorbent. In accordance with one preferred embodiment, the separator is a dialysis bag contained in the transparent reactor vessel into which the resin is placed. The at least one solvent soluble constituent is then removed from the at least one sorbent through the separator.

Zero headspace extractor and method for determining partitioning and contaminant release rates of volatile and semi-volatile compounds

A process for remediation of contaminated solid materials comprising polynuclear aromatic hydrocarbon contaminated solid materials, polychlorinated hydrocarbon contaminated materials, and mixtures thereof by sequential biological/chemical/biological treatment in which the contaminated solid materials are biodigested under suitable conditions by a first aerobic or anaerobic digestion, producing a first biodigestion product. The first biodigestion product is then contacted for chemical treatment with hydrogen peroxide in the presence of ferrous ion in amounts and under conditions suitable for chemical oxidation, forming a mixture and oxidizing the first biodigestion product, producing biodegradable hydrocarbon product materials having enhanced biodegradability. The product materials are then biodigested under suitable conditions by a second aerobic or anaerobic digestion.

Sequential biological/chemical/biological treatment of organic waste

A fermentation process for making succinic acid in high concentrations employs a bacteria obtained from the rumen contents of cattle. A preferred bacteria is Bacterium 130Z (ATCC No. 55618).
