摘要
The invention relates to the recovery of precious metal lost from precious metal-containing catalysts for example the precious metal-containing catalysts which are used in the production of nitric acid by ammonia oxidation. In more detail, a getter (as herein defined) for recovery of precious metal lost from a precious metal-containing catalyst operating at elevated temperature comprises an agglomeration or assemblage of unwoven fibres made from a metal selected from the group ruthenium, palladium, iridium, platinum, gold, silver, rhodium and alloys containing one or more of the said metals. Preferably, the unwoven fibres are randomly oriented.
