In this work, the separation of Rh (III) from Pd (II) and Pt (IV) in a hydrochloric acid (HCI) solution was studied using a m-phenylene diamine-containing precipitant (m-PDA). At high HCI concentrations (6.0-8.0 M), most of the Rh (III) (>90%) was precipitated, and Pd (II) and Pt (IV) were hardly precipitated (<5%). On the other hand, over 85% of Pd (II) and Pt (IV) precipitated along with small amount of Rh (III) (<25%) at low HCI concentrations (1.0-2.0 M). As a consequence, m-PDA enabled selective and preferential precipitation of Rh (III) at high HCI concentrations. XPS and TG analyses revealed that the Rh-containing precipitate is an ion-pair complex composed of one [RhCI6](3-) anion and three m-PDA cations. The Rh desorption from the precipitate as well as the recovery of m-PDA was successfully achieved using an NH4OH solution. This method is a promising practical approach to Rh recovery.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Nature Research"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/s41598-019-48920-9","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_25":{"attribute_name":"関連リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://dx.doi.org/10.1038/s41598-019-48920-9"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1038/s41598-019-48920-9","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"著作権等","attribute_value_mlt":[{"subitem_rights":"This article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
