REMOVAL OF GERMANIUM FROM GASEOUS EFFLUENT DURING OPTICAL FIBER MANUFACTURING PROCESS

摘要

Recovery of germanium from the effluent of optical fiber manufacturing processes depends on the realization that the germanium is to a substantial extent in gaseous form. Thus, to separate the germanium effectively appropriate measures are taken to separate not only particulate matter but also gaseous germanium compounds. This separation is done through among other steps an appropriate solvation and precipitation to remove the gaseous germanium material.
