Disk-like pellets compacting the anhydrous sulfate powders were used. The decomposition occurred at the phase boundary between the undecomposed sulfate and the oxide product, and the boundary proceeded uniformly from the surface towards the interior. The thickness, x, of the oxide product layer was proportional to the time, t, for Fe2（SO4）3, C0SO4 and NiSO4 : the rate equation was x=kct. The x vs t curves for CuSO4 and ZnSO4 were shown to become two straight lines with a break point. From the kinetic data and the results of X－ray diffraction, it was known that the break is due to the formation of their oxyysulfate as the intermediate. The in k vs 1/T relationship moves from lower to higher temperatures in the order : Fe2（SO4）3, CuSO4, CoSO4, NiSO4, ZnSO4. The activation energies of the decomposition for sulfates of iron（III）, cobalt, nickel, copper and zinc were 212, 217, 257, 211 and 238 kJ mo1-1, and those for oxysulfates of copper and zinc at the later stage after the break were 221 and 275 kJmo1-1, respectively, The activation energies were shown to be close to the enthalpies of decomposition for the sulfates, ⊿H゜d298","subitem_description_type":"Abstract"}]},"item_6_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"タガワ, ヒロアキ"}]},{"nameIdentifiers":[{}],"names":[{"name":"サイジョウ, ヒロユキ"}]}]},"item_6_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"Tagawa, Hiroaki"}]},{"nameIdentifiers":[{}],"names":[{"name":"Saijo, Hiroyuki"}]}]},"item_6_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00246482","subitem_source_identifier_type":"NCID"}]},"item_6_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286584X","subitem_source_identifier_type":"ISSN"}]},"item_6_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"横浜国立大学環境科学研究センター汚染拡散学研究室 = Department of Environmental Energy Chemistry, Institute of Environmental Science and Technology, Yokohama National University"},{"subitem_text_value":"横浜国立大学環境科学研究センター汚染拡散学研究室 = Department of Environmental Energy Chemistry, Institute of Environmental Science and Technology, Yokohama National University"},{"subitem_text_value":"横浜国立大学環境科学研究センター汚染拡散学研究室 = Department of Environmental Energy Chemistry, Institute of Environmental Science and Technology, Yokohama National University"}]},"item_6_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田川, 博章"}],"nameIdentifiers":[{"nameIdentifier":"24642","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西候, 宏之"}],"nameIdentifiers":[{"nameIdentifier":"24643","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-09-20"}],"displaytype":"detail","filename":"biest121097.pdf","filesize":[{"value":"461.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"biest121097.pdf","url":"https://ynu.repo.nii.ac.jp/record/5278/files/biest121097.pdf"},"version_id":"806cb3dd-8336-4fd7-8050-d7747b62f0dc"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"遷移金属硫酸塩の熱分解の速度と機構","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"遷移金属硫酸塩の熱分解の速度と機構"}]},"item_type_id":"6","owner":"3","path":["535"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-08-23"},"publish_date":"2010-08-23","publish_status":"0","recid":"5278","relation_version_is_last":true,"title":["遷移金属硫酸塩の熱分解の速度と機構"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T21:08:31.693875+00:00"}
