摘要： An object of the present invention is to provide a structure of a metal collecting material for use in seawater or river water or industrial wastewater to give the most excellent adsorption efficiency. Another object of the present invention is to provide a process for efficiently separating and recovering valuable metals or noxious metals from a metal collecting material having collected said valuable metals from seawater or noxious metals from river water or wastewater with the least possible waste generation.A metal collector according to an aspect of the present invention is formed by stacking at least partially alternate layers of a fibrous metal collecting material with a spacer for introducing a liquid to be treated into said collecting material, wherein the area of spacer side faces represents 25-75% of the total area of collecting material side faces and spacer side faces in the side faces of the stack. A process for eluting and recovering a metal from a metal collecting material according to another aspect of the present invention comprises the steps: (1) contacting the metal collecting material having absorbed a metal with a dilute eluent, (2) contacting the metal collecting material with an eluent more concentrated than in step 1 to recover the metal into the eluent; and (3) contacting a metal resorbing material with the eluate from step 2 to resorb the metal.

摘要： A method for producing hydrogen wherein use is made of a high temperature steam electrolysis apparatus having an electrolysis vessel being partitioned into the anode side and the cathode side by the use of a solid oxide electrolyte film as a diaphragm, steam is fed to the above cathode side and a reducing gas is fed to the anode side, and steam electrolysis is carried out at a high temperature, characterized in that the reducing gas and the steam fed to the electrolysis vessel has a temperature of 200 to 500° C. The above temperature range for the reducing gas and the steam fed to the electrolysis vessel has been found to be an optimum temperature range, as a result of taking the heat balance within the vessel into consideration, in a high temperature steam electrolysis apparatus wherein a solid oxide electrolyte film is used, a reducing gas is fed to the anode side and steam is fed to the cathode side, an oxygen ion is allowed to react with said reducing gas on the cathode side, to thereby generate a concentration gradient for an oxygen ion and thus reduce an electrolysis voltage.
