Supercritical extraction and prospects for the creation of new waste-free products

The principal ideals underlying a new separation procedure – supercritical extraction – are described and its advantages and disadvantages are considered. The properties of supercritical gases such as solvent power and selectivity are discussed. The possibilities of supercritical extraction in solving applied problems in environment protection are demonstrated: purification of waste waters, regeneration of sorbents, detoxification of toxicants. The bibliography includes 32 references.
