Wege bildet. Die aus dem geschilderten Verfahren entstandenen Niederschläge können gesammelt und gegebenenfalls verascht werden. Das Fällungsmittel kann aus den Aschen als Oxyd des säurebildenden Metalles, mit dem Alkali verbunden war, wiedergewonnen werden und durch Auflösen dieses Oxydes in Natronlauge erneuert und wiederum zum Ausfällen der organischen

Die Vorteile des neuen Verfahrens, das, wie bereits erwähnt, von einem Verdampfen der

Forms ways. The precipitates resulting from the process described can be collected and, if necessary, incinerated. The precipitant can be recovered from the ashes as the oxide of the acid-forming metal with which the alkali was bound and renewed by dissolving this oxide in caustic soda and again for the precipitation of the organic

The advantages of the new process, which, as already mentioned, of an evaporation of the
