The similar adsorption phenomena can be observed for ice crystal in water containing several ions. In this study, adsorption of phosphate and ammonium ions on ice crystals was examined experimentally by keeping spherical ice crystals in the solution prepared with phosphate and ammonium salts, they were chosen as pollutant substances occurring the eutrophication of lake water. At adsorption of the ions on ice crystals, it was able to discriminate a comparatively large selectivity between phosphate and ammonium ions. This phenomena was a physical adsorption with the influence of hydrogen bonds on the ice surface. This adsorption was a Langmuir-adsorption type. Adsorption capacity was existed at the range of 0.2-0.6℃, and the adsorption amount at about 0.2 min was found to be larger than that observed after 0.2 min. It should be noted that temperature plays an important role to deal with ice crystals functioning as usual adsorbents. Besides, recovery of the ions was comparatively easier than usual adsorbents because dissolution-water on early stage of ice crystals that adsorbed the ions had higher concentration of the ions than the dissolution-water on later stage. It is expected that adsorption of phosphate and ammonium ions on ice crystals plays an important role for the purity of water pollution in ponds, lakes, swamps, and so on.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "161201", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ando, Teruyoshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "161202", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Taguchi, Yoji"}]}, {"nameIdentifiers": [{"nameIdentifier": "161203", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Aoyama, Kiyomichi"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学積雪地域災害研究センター"}]}, "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": "AN00183327", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03877892", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "安東, 照喜"}], "nameIdentifiers": [{"nameIdentifier": "161198", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "田口, 洋治"}], "nameIdentifiers": [{"nameIdentifier": "161199", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "青山, 清道"}], "nameIdentifiers": [{"nameIdentifier": "161200", "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": "19_97-102.pdf", "filesize": [{"value": "403.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 403500.0, "url": {"label": "19_97-102.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28043/files/19_97-102.pdf"}, "version_id": "25c2dcac-9f37-4b85-ac33-ff0e6f2d1952"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Adsorption", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Phosphate ion", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Ammonium ion", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Ice crystal", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Water pollution", "subitem_subject_scheme": "Other"}, {"subitem_subject": "吸着", "subitem_subject_scheme": "Other"}, {"subitem_subject": "リン酸イオン", "subitem_subject_scheme": "Other"}, {"subitem_subject": "アンモニウムイオン", "subitem_subject_scheme": "Other"}, {"subitem_subject": "氷結晶", "subitem_subject_scheme": "Other"}, {"subitem_subject": "水質汚濁", "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": "リン酸及びアンモニウムイオンの氷結晶への吸着に関する研究  (大木靖衛教授退官記念号）", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "リン酸及びアンモニウムイオンの氷結晶への吸着に関する研究  (大木靖衛教授退官記念号）"}, {"subitem_title": "リン酸及びアンモニウムイオンの氷結晶への吸着に関する研究  (大木靖衛教授退官記念号）", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1564"], "permalink_uri": "http://hdl.handle.net/10191/39181", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-03-04"}, "publish_date": "2016-03-04", "publish_status": "0", "recid": "28043", "relation": {}, "relation_version_is_last": true, "title": ["リン酸及びアンモニウムイオンの氷結晶への吸着に関する研究  (大木靖衛教授退官記念号）"], "weko_shared_id": null}
