    Abstract: An apparatus and process for hydrogen peroxide vapor sterilization of medical instruments and similar devices make use of hydrogen peroxide vapor released from an inorganic hydrogen peroxide complex. The peroxide vapor can be released at room temperature and atmospheric pressure; however, the pressure used can be less than 50 torr and the temperature greater than 86 DEG C to facilitate the release of hydrogen peroxide vapor. Preferred hydrogen peroxide complexes for use in the invention include Na4P2O7.3H2O2 and KH2PO4.H2O2. The heating rate can be greater than 5 DEG C. Optionally, a plasma can be used in conjunction with the vapor.

    Abstract: The invention provides a unique, efficient and cost-effective process for the recovery of acid from acid-rich solutions. The process of the invention utilizes a strong oxidizer, such as Caro's acid, to disintegrate or render insoluble organic or inorganic materials such as carbohydrates and complexes thereof contained in acid-rich solutions, to make efficient and simple the separation and recovery of the acid solution. The acid recovered thus obtained is free of organic matter, and containing nearly all of the acid originally contained in the acid-rich solution.
