【摘要】 本文讨论了钌同硫脲的显色反应，在不经分离的条件下，将Ｒｕ还原Ｒｕ￣Ⅱ，Ｒｕ￣Ⅱ与硫脲生成蓝色，λ＿最大＝６３５ｎｍ，在０－３００μｇ／ｍｌ范围内呈线性关系。本法适宜测定含Ｒｕ量较高钌的渣及其选矿成品。更多还原

【Abstract】 The determination of ruthenium used to be determined through distillation,fractiona-tion and enrichment. But the authors improve the method which ruthenium is reduced intoRu￣Ⅱ by reductant. Ru￣Ⅱ with thiourea forms a blue complex. λ_max=635nm. In the range of 0-300μg/ml,the content of ruthenium obeys Beer′s Law. This method has been applied to thedetermination of Ru in ruthenium slag.更多还原
