【発明の名称】水中の酸素-、亜硝酸塩-及び/又は硝酸塩含量を除去する方法
Document Type and Number:
Japanese Patent JPH08506987
Kind Code:
A
Abstract:
Catalytic supports covered with rhodium, palladium or palladium and copper have been found to be highly suitable for use as catalysts in the method proposed for removing oxygen, nitrites and/or nitrates from aqueous systems or reducing the oxygen, nitrite and/or nitrate concentration in such systems. The oxidic support (preferably made from aluminium oxide) consists of spherical particles produced by spraying or dropping a sol into a zone containing a reactive gas. The sol droplets assume a spherical shape, are allowed to presolidify and then collected. The particles obtained following drying and calcining are then covered with the catalytically active substance(s).
