VERFAHREN UND VORRICHTUNG ZUR MESSUNG VON CYANID.

摘要

A system for measuring cyanides in a sample employs a photoillumination component for producing ultraviolet radiation to dissociate cyanides contained in an alkaline sample. The system includes filtering components interposed between the photoillumination components and an alkaline sample to be tested for passing lower frequency ultraviolet radiation to produce an irradiated sample in which cyanides have been dissociated, while blocking high frequency ultraviolet radiation to inhibit thiocyanate dissociation. Thin-film distillation components are included for separating cyanide from the irradiated sample to produce recovered cyanide for measurement purposes, and measuring components are provide for receiving the recovered cyanide generating a recordable signal indicative of recovered cyanide quantity.
