IPC: C25D21/14
Filed: 1992-09-07
Abstract: PURPOSE:To prevent decrease in the dissolving speed of a metallic zinc at the time of dissolving the metallic zinc in solvent by blowing a gas against the metal zinc to remove the Ni layer depositing on the metal zinc. CONSTITUTION:Continuous Zn-Ni alloy electroplating is conducted in an acidic bath using an insoluble anode. In this case, the quantity of the plating soln. received from a plating tank 8 is measured by a flowmeter 9 to determine the quantity of metal zinc to be dissolved and supplied to a zinc dissolving tank 1 through a nozzle 5. A metal zinc lump is introduced into the soln. as the plating soln. housed in the dissolving tank 1, and a gas (air, nitrogen, oxygen, etc.) is blown into the soln. from a nozzle 6 to remove the Ni layer or Ni alloy layer depositing on the metal zinc. Consequently, the dissolution of metal zinc is promoted, and cost is drastically reduced.

Title: Production of platinum sponge
Inventor: MOCHIZUKI MITSUAKI
IPC: B01D53/86
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To make the surface, of platinum porous like sponge while keeping the platinum in wire or plate-like shaped state as it is by applying a Na nitride to a linear or plate-like shaped platinum body and heating the platinum body in a reductive atmosphere within a specified temperature range. SOLUTION: A platinum wire is inserted into a magnetic pipe, the pipe is filled with sodium azide, and the resultant pipe is put in a furnace in a reductive atmosphere and heated not lower than 300 deg.C and not higher than 800 deg.C for a prescribe time. By the treatment, the original platinum wire is getting thick and the surface becomes porous and the fine pores are evenly distributed. Platinum originally has excellent catalytic function and in the practical use of platinum as a catalyst, it is preferable that the ratio of the total surface area/outer part surface area, that is the specific surface area, is high and a platinum sponge is used for catalytic use and in this case, the surface area is increased by making the surface area porous while keeping the linear or plate-like shaped body of platinum as it is.  Moreover, since the surface of platinum is made porous like a sponge while the linear or plate like shaped body is kept as it is, the structure of the catalytic cylinder can be simplified and dust adhesion to the surface of the catalyst layer is lessened and dust is easily wiped out.
