Two types of polymerization degrees (1700 and 2500) of PVA were used in this experiment. The gel volume in water was induced at around 310 K for 1700 and 320 K for 2500. At higher temperatures, the temperature sensitive polymer gel shrinks because of discharging water, whereas, in contrast, at lower temperatures, the gel swells as a result of absorbing water. The reversibility of the volume change of the synthesized polymer gel is confirmed by changing temperature.The adsorption behavior of organic compounds onto PVA polymer gels in water was investigated at various temperatures. The amount of adsorption of organic compounds increases remarkably at temperatures higher than about 310 K for 1700 and 320 K for 2500. The organic compound in water could be adsorbed and desorbed reversibly onto PVA polymer gel by the temperature swing. The mechanism of adsorption and desorption of organic compounds onto gel can be explained by the hydration and dehydration of the polymer gel. The driving force of the adsorption is thought to be the hydrophobic interaction between PVA polymer gel and organic compounds.","subitem_description_type":"Other"}]},"item_9_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"25197","nameIdentifierScheme":"WEKO"}],"names":[{"name":"山本, 秀樹"}]},{"nameIdentifiers":[{"nameIdentifier":"25198","nameIdentifierScheme":"WEKO"}],"names":[{"name":"部屋本, 範幸"}]},{"nameIdentifiers":[{"nameIdentifier":"25199","nameIdentifierScheme":"WEKO"}],"names":[{"name":"芝田, 隼次"}]}]},"item_9_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Society of Chemical Engineers"}]},"item_9_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1252/jcej.36.506","subitem_relation_type_select":"DOI"}}]},"item_9_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00709658","subitem_source_identifier_type":"NCID"}]},"item_9_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00219592","subitem_source_identifier_type":"ISSN"}]},"item_9_text_35":{"attribute_name":"出版者（他言語）","attribute_value_mlt":[{"subitem_text_value":"化学工学会"}]},"item_9_version_type_17":{"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":"Yamamoto, Hideki"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Heyamoto, Noriyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shibata, Junji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-23"}],"displaytype":"detail","filename":"KU-1100-20030401-14.pdf","filesize":[{"value":"201.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-20030401-14.pdf","url":"https://kansai-u.repo.nii.ac.jp/record/11277/files/KU-1100-20030401-14.pdf"},"version_id":"0985c7b6-937f-42bd-8e73-eafd0e048883"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Temperature-Sensitive Gel","subitem_subject_scheme":"Other"},{"subitem_subject":"Polyvinylalcohol","subitem_subject_scheme":"Other"},{"subitem_subject":"Volume Change","subitem_subject_scheme":"Other"},{"subitem_subject":"Adsorption","subitem_subject_scheme":"Other"},{"subitem_subject":"Removal","subitem_subject_scheme":"Other"},{"subitem_subject":"1, 2-Dichloroethane","subitem_subject_scheme":"Other"},{"subitem_subject":"Temperature Swing","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":"Removal of Harmful Organic Compounds in Water Using Temperature-Sensitive Polymer Gel","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Removal of Harmful Organic Compounds in Water Using Temperature-Sensitive Polymer Gel"}]},"item_type_id":"9","owner":"1","path":["1594"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-11-09"},"publish_date":"2011-11-09","publish_status":"0","recid":"11277","relation_version_is_last":true,"title":["Removal of Harmful Organic Compounds in Water Using Temperature-Sensitive Polymer Gel"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-15T14:33:22.967364+00:00"}
