摘要
PROBLEM TO BE SOLVED: To provide a nitric acid reduction catalyst composition which is applicable even to a high-concentration nitric acid solution and is capable of efficiently reducing a nitrate ion, nitrite ion and the like, and to provide a processing method of a nitric acid solution using the same.;SOLUTION: The nitric acid reduction catalyst composition contains platinum, copper and tin. The processing method of the nitric acid solution comprises the step of bringing the nitric acid solution into contact with hydrogen gas in the presence of the nitric acid reduction catalyst composition.;COPYRIGHT: (C)2007,JPO&INPIT
