In addition, fluoride is remarkably one among the constituents of this waste material. Experimental studies were conducted to determine the fluoride leaching as a function of particle size, pH of leaching solvent (distilled water) and water: PBP ratio. The influence of sodium salts on the leaching of fluoride from PBP was studied. It was explored that one gram of plaster board waste contains 18.54 mg F per gram of PBP. High leaching of 3.70 mg F per liter was studied at pH 6.02 with Ca2+ and TDS contents of 1050 mg L-1 and 1640 mg L-1 respectively. The influence of fluoride leaching by sodium phosphate recorded a high value of 12.75 mg L-1 with no detectable amount of calcium ions. The leaching mechanism was predicted significantly by the exchange of Na+ and Ca2+ ions. The leaching rate as a consequence of shaking and stirring dynamics was also investigated at different conditions.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学大学院工学研究科研究報告, 48(90), pp.45-56; 2018","subitem_description_type":"Other"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学大学院工学研究科"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12601998","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18805574","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"08"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Engineering, Nagasaki University"}]},"item_3_version_type_16":{"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":"Sivasankar, Venkataraman"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Omine, Kiyoshi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-21"}],"displaytype":"detail","filename":"48_90_45.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"48_90_45.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/2715/files/48_90_45.pdf"},"version_id":"f41cbd9b-cd8e-4c04-bcca-7ca8dca79ff0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Plaster board","subitem_subject_scheme":"Other"},{"subitem_subject":"fluoride leaching","subitem_subject_scheme":"Other"},{"subitem_subject":"characterizations","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Chemistry of Fluoride Leaching and Associating Influential Factors in Plaster Board Waste","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Chemistry of Fluoride Leaching and Associating Influential Factors in Plaster Board Waste"}]},"item_type_id":"3","owner":"2","path":["201"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-01-29"},"publish_date":"2018-01-29","publish_status":"0","recid":"2715","relation_version_is_last":true,"title":["Chemistry of Fluoride Leaching and Associating Influential Factors in Plaster Board Waste"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T03:42:17.067924+00:00"}
