Title: Method for removing iron from liquid containing iron
Inventor: NAGAHAMA TATSUYA
IPC: C01G49/06
Filed: 1979-12-28
Abstract: PURPOSE: To separate and remove iron from a liquid containing iron as an ethylene diamine tetraacetatic acid (EDTA)-ferric chelate compound, by precipitating a ferric hydroxide by adding a strong alkali agent to the liquid.  
     CONSTITUTION: To a liquid, such as waste photographic processing water, containing iron as an ethylene diamine tetraacetatic acid-ferric chelate compound, a strong alkali agent, such as a sodium hydroxide and calcium hydroxide, is added. Then, the compound is decomposed and the iron is precipitated as a ferric hydroxide. Later, the precipitate of this ferric hydroxide is separated in the solid-liquid separating method. Thus, the iron can efficiently be removed from the liquid containing the iron as the EDTA-ferric chelate compound.

Abstract: PURPOSE: To form a highly scratch-resistant outermost protective layer on a recording layer by separating a temporary support from an adhesive layer assemblage through separating the assembled layers, and chemically curing and forming a specific outermost protecting layer consisting of a multilayer assemblage. CONSTITUTION: An adhesive layer 22 is formed by applying a solution of methylethyl ketone (styrene/butylmethacrylate) (70/30) on one side of a polyethylene terephthalate film acting as a temporary support 24. This film material is brought into contact with a new vacuum-deposited bismuth layer 21 and is attached on the surface of a permanent polyethylene terephthalate resin support 20 through the adhesive layer 22.
