Commercial calcined hydrotalcite was used in first step to reduce Cl^- content in seawater. Two types of Japanese natural zeolite, mordenite-type zeolite (Iizaka mine, Fukushima prefecture) and clinoptilolite-type zeolite (Koriyama mine, Kagoshima prefecture) were used in second step to reduce Na^+ concentration. Cl^- in seawater can be reduced by calcined hydrotalcite to obtain anion-reduced solution; Na^+ can be reduced by ion exchange with both types of natural zeolite. The obtained solution was neutral, and included the nutrients K^+, Mg^<2+>, and Ca^<2+>, and low levels of Na^+ and Cl^-. Higher concentrations of K^+, Mg^<2+> and Ca^<2+> in the solution can be obtained by mordenite-type Iizaka natural zeolite than those by clinoptilolite-type Koriyama natural zeolite. Radish sprouts did not grow in seawater and anion-reduced solution, but they grew in both solutions after zeolite treatment.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本粘土学会"}]},"item_10001_rights_15":{"attribute_name":"著作権等","attribute_value_mlt":[{"subitem_rights":"日本粘土学会"}]},"item_10001_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA00607148","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00098574","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"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":"WAJIMA, TAKAAKI"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHIMIZU, TOMOE"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMATO, TAKEHIKO"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"IKEGAMI, YASUYUKI"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"wajima11.pdf","filesize":[{"value":"996.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"wajima11.pdf","url":"https://air.repo.nii.ac.jp/record/2089/files/wajima11.pdf"},"version_id":"712eeed9-6b51-4e1d-9952-ec1e60860334"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Agricultural cultivation","subitem_subject_scheme":"Other"},{"subitem_subject":"solution","subitem_subject_scheme":"Other"},{"subitem_subject":"Calcined hydrotalcite","subitem_subject_scheme":"Other"},{"subitem_subject":"Natural zeolite","subitem_subject_scheme":"Other"},{"subitem_subject":"Radish sprout","subitem_subject_scheme":"Other"},{"subitem_subject":"Seawater","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":"SIMPLE TWO-STEP PROCESS FOR MAKING AGRICULTURAL CULTIVATION SOLUTION FROM SEAWATER USING CALCINED HYDROTALCITE AND NATURAL ZEOLITE","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"SIMPLE TWO-STEP PROCESS FOR MAKING AGRICULTURAL CULTIVATION SOLUTION FROM SEAWATER USING CALCINED HYDROTALCITE AND NATURAL ZEOLITE"}]},"item_type_id":"10001","owner":"3","path":["630"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-09-10"},"publish_date":"2013-09-10","publish_status":"0","recid":"2089","relation_version_is_last":true,"title":["SIMPLE TWO-STEP PROCESS FOR MAKING AGRICULTURAL CULTIVATION SOLUTION FROM SEAWATER USING CALCINED HYDROTALCITE AND NATURAL ZEOLITE"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T11:33:24.544038+00:00"}
