从废钯/炭催化剂中回收金属钯
Recovery of Palladium from Waste Palladium/Carbon Catalyst
摘要
Abstract
palladium was recovered from waste palladium/carbon catalyst by the incineration-formic acid reduction-aqua regia dissolution-crystallization-zinc particle replacement process. For the aqua regia dissolution step, the effects of reaction temperature, reaction time and aqua regia dosage on the palladium recovery were studied. Under the conditions of reaction temperature 80-90℃, reaction time 8.0 h, m(palladium fine residue) : m(aqua regia)=l: 8, palladium recovery is about 97.0%.关键词
