Simazine (6-chloro-N2, N4-diethyl-1, 3, 5-triazine-2, 4-diamine) is a chlorinated s-triazine herbicide that is widely used in agriculture for the control of various weeds. As a result of drifts or runoffs, simazine has been detected as a relatively persistent pollutant, which can become an endocrine disrupter and a carcinogen, in soil and water in areas adjacent to farmlands. Therefore, bioremediation is considered to be a highly promising technology for the removal of environmental pollutants. In the present study, char and activated char were prepared from moso-bamboo and were examined about the property of both absorption and desorption of simazine. For comparison, commercial activated carbon was purchased. In the case of simazine absorption, bamboo char absorbed smaller amount than its activated carbon. Two activated carbons, prepared and purchased, indicated same absorbing capacity in higher rate and larger amount. Desorption test was performed using absorbed chars. Approximately 50％ of simazine absorbed in the bamboo char are released during desorption test for two weeks. Almost of simazine absorbed in the both activated carbons were not desorbed and fixed in the activated carbon.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "162387", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kojima, Yasuo"}]}, {"nameIdentifiers": [{"nameIdentifier": "162388", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kato, Yoshiaki"}]}, {"nameIdentifiers": [{"nameIdentifier": "162389", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Fukumitsu, Satomi"}]}, {"nameIdentifiers": [{"nameIdentifier": "162390", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ohara, Kouki"}]}, {"nameIdentifiers": [{"nameIdentifier": "162391", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Shimizu, Ryo"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学農学部"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00183393", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03858634", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "小島, 康夫"}], "nameIdentifiers": [{"nameIdentifier": "162382", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "加藤, 喜明"}], "nameIdentifiers": [{"nameIdentifier": "162383", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "福光, 里美"}], "nameIdentifiers": [{"nameIdentifier": "162384", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "大原, 功輝"}], "nameIdentifiers": [{"nameIdentifier": "162385", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "清水, 亮"}], "nameIdentifiers": [{"nameIdentifier": "162386", "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": "2019-08-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "68_31-35.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "68_31-35.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28267/files/68_31-35.pdf"}, "version_id": "f70eed95-4792-4878-917e-76b050aa8983"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "竹炭", "subitem_subject_scheme": "Other"}, {"subitem_subject": "活性炭", "subitem_subject_scheme": "Other"}, {"subitem_subject": "simazine", "subitem_subject_scheme": "Other"}, {"subitem_subject": "吸着", "subitem_subject_scheme": "Other"}, {"subitem_subject": "脱着", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Bamboo char", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Activated carbon", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Absorption", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Desorption", "subitem_subject_scheme": "Other"}]}, "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": "竹炭および竹活性炭による農薬Simazine の吸着と脱着", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "竹炭および竹活性炭による農薬Simazine の吸着と脱着"}, {"subitem_title": "竹炭および竹活性炭による農薬Simazine の吸着と脱着", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1586"], "permalink_uri": "http://hdl.handle.net/10191/39813", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-03-16"}, "publish_date": "2016-03-16", "publish_status": "0", "recid": "28267", "relation": {}, "relation_version_is_last": true, "title": ["竹炭および竹活性炭による農薬Simazine の吸着と脱着"], "weko_shared_id": null}
