In this study, the extraction reaction of Pd(II) in chloride media using of N, N, N’, N’, N”, N”-hexaoctyl-nitrilotriacetamide (NTAamide(C8)) as a novel extractant has been demonstrated. Three diluents with high dielectric constants (acetophenone (AP), 1,2-dichloroethane (DCE), and 1-octanol (OC)) were used for the solvent extraction reaction. The slope analysis indicated that the anion exchange extraction reaction of Pd(II) was consistent with an approximately 2:1 stoichiometry for the NTAamide(C8)/AP and NTAamide(C8)/DCE systems, and 1:1 for NTAamide(C8)/OC. Moreover, the ED behavior of the extracted Pd(II) complex was investigated using cyclic voltammetry (CV). Palladium reduction was found to be an irreversible process based on analysis of the standard rate constant. A semi-integral analysis of the voltammogram determined the diffusion coefficients of the extracted Pd(II) complex in the AP, DCE, and OC systems to be 3.7 ± 0.1 × 10−10, 2.8 ± 0.1 × 10−10 and 1.5 ± 0.2 × 10−10 m2 s−1, respectively. Furthermore, consecutive extraction-electrodeposition processes using the NTAamide(C8)/AP system were carried out for five cycles. High extraction percentage (E > 91%) and current efficiency (ε > 83.1%) were attained in all cycles. The electrodeposits recovered from the extraction-electrodeposition process were identified as Pd metal through X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) analyses.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Taylor & Francis"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1080/07366299.2021.2023268","subitem_relation_type_select":"DOI"}}]},"item_2_relation_44":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://doi.org/10.1080/07366299.2021.2023268"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1080/07366299.2021.2023268","subitem_relation_type_select":"DOI"}}]},"item_2_rights_14":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"This is an Accepted Manuscript of an article published by Taylor & Francis in Solvent Extraction and Ion Exchange on 05 Jan 2022, available at: http://www.tandfonline.com/10.1080/07366299.2021.2023268"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"15322262","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Environment and Information Sciences, Yokohama National University"},{"subitem_text_value":"Graduate School of Environment and Information Sciences, Yokohama National University"},{"subitem_text_value":"Nuclear Science and Engineering Directorate, Japan Atomic Energy Agency"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ryoma, Kinoshita"}],"nameIdentifiers":[{"nameIdentifier":"43361","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masahiko, Matsumiya"}],"nameIdentifiers":[{"nameIdentifier":"34887","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"00370057","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=00370057"}]},{"creatorNames":[{"creatorName":"Yuji, Sasaki"}],"nameIdentifiers":[{"nameIdentifier":"40666","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20354839","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=20354839"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-01-05"}],"displaytype":"detail","filename":"revised2_N21-35_pre_ed_rev_final.pdf","filesize":[{"value":"889.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"revised2_N21-35_pre_ed_rev_final.pdf","url":"https://ynu.repo.nii.ac.jp/record/12166/files/revised2_N21-35_pre_ed_rev_final.pdf"},"version_id":"ca669a3a-31dd-4c52-b884-d67896eb666b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Chloride media","subitem_subject_scheme":"Other"},{"subitem_subject":"extraction-electrodeposition","subitem_subject_scheme":"Other"},{"subitem_subject":"NTAamide(C8)","subitem_subject_scheme":"Other"},{"subitem_subject":"palladium","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Recovery of Palladium by Extraction-electrodeposition Using N, N, N’, N’, N”, N”- Hexaoctyl-nitrilotriacetamide","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Recovery of Palladium by Extraction-electrodeposition Using N, N, N’, N’, N”, N”- Hexaoctyl-nitrilotriacetamide"}]},"item_type_id":"2","owner":"3","path":["501"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-11-01"},"publish_date":"2022-11-01","publish_status":"0","recid":"12166","relation_version_is_last":true,"title":["Recovery of Palladium by Extraction-electrodeposition Using N, N, N’, N’, N”, N”- Hexaoctyl-nitrilotriacetamide"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T17:38:41.208892+00:00"}
