摘要： The invention is directed to a process of purifying metal fluoride materials used to make metal fluoride single crystals suitable for making optical elements used in the transmission of wavelengths below 200 nm, and in particular to a process of purifying such materials by the use of a halogen containing plasma to convert metal oxygenates contaminating the feedstocks used in the preparation of the crystals to metal fluorides. The invention also is directed to a process of growing a metal fluoride single crystal using a crystal growth furnace to carry out the foregoing purification procedure followed by the steps of melting the purified material and cooling it using s selected time and temperature cycle to from a metal fluoride single crystal. The plasmas used in practicing the invention can be derived from a variety of halogenated materials including, for example, fluorocarbons, chlorocarbons, boron trihalides, chlorine, fluorine, xenon difluoride and other gaseous or easily volatilized halogenated substances known in the art.

摘要： A system for adsorbing a plurality of contaminants from a workstream composed of a first stage open-ended activated carbon monolith adsorber, a second stage open ended activated carbon monolith adsorber downstream of the first stage. The first stage activated carbon has an average pore size that is larger than the average pore size of the second stage activated carbon. A method for removing more than one contaminant from a workstream which involves passing a workstream containing more than one contaminant through a first open ended activated carbon monolith adsorber having a pore size suitable for adsorbing the major portion of the larger size contaminant and for allowing the smaller size contaminant to pass through the monolith, to cause adsorption of the major portion of the larger size contaminant by the activated carbon, while allowing the smaller size contaminant to pass through the first monolith, and thereafter passing the effluent from the first adsorber through a second open ended activated carbon monolith adsorber having a pore size suitable for adsorbing the smaller size contaminant to cause adsorption of the major portion of the smaller size contaminant by the second monolith activated carbon. The adsorbed contaminants can then be desorbed by passing a regenerating stream(s) through the respective monoliths.
