摘要： PROBLEM TO BE SOLVED: To remove organic components containing bivalent phenol and/or the oxidant thereof in a waste liquid. SOLUTION: The pH of a waste liquid containing bivalent phenol such as hydroquinone and/or benzoquinone and/or the oxidant thereof is adjusted to 7 to 13, thereafter, a peroxodisulfate is added thereto, next, a pH adjusting agent is added thereto, so as to adjust the pH to 1 to 4. In this way, at least a part of the hydroquinone and/or benzoquinone is polymerized, and also, the polymer is coagulated-settled, so as to be removed. The peroxodisulfate is a polymerization initiator effective for the hydroquinone or the like, and the hydroquinone or the like in the waste liquid are polymerized to be higher molecule, thus their removal by filtering is facilitated.

摘要： PROBLEM TO BE SOLVED: To eliminate defects of hydrazine fuel cell or the like having a low oxidation activity of fuel. SOLUTION: A fuel electrode is made by forming a hydrogen storage alloy into a film on a current collector material of foam metal. The current collector material of foam metal satisfies characteristics of being large in a reaction area, small in electric resistance and its electrode not breaking down and the hydrogen storage alloy is endowed with oxidation activity of fuel which can not be found in an electrode for a conventional alkaline fuel cell. Therefore, the fuel electrode with the both requisites can be a highly efficient fuel cell in many aspects. COPYRIGHT: (C)2005,JPO&NCIPI
