Thiol group and -NH (RCOOH) group were selected as such functional groups. Several methods were carried out for introduction of the functional groups. (1) Some halogenoacetals of polyvinyl alcohol are treated with NaSH. (2) After the halogenoacetals are treated with Na_3Sx, the products are reduced by NaHSO_3. From (1) and (2) polyvinyl alcohol derivatives containing SH group are obtained. (3) Aminoacetals of polyvinyl alcohol synthesized by the reaction between polyvinyl alcohol and aminoacetals are treated with monochloroacetic acid. (4) polyvinyl alcohol is acetalized by aminoacetal containing carbonic acid group. From (3) and (4) polyvinyl alcohol containing NH_2 group and carbonic acid in the former' s neighbourhood is obtained.　Adsorption capacity of these polymers for Hg^ and Cd^ in aqueous solution was examined. Among them, polymers obtained by method (3) show the strongest adsorption capacity for Hg^, then polymer obtained by method (1) follows. Polymers obtained by method (1) and (3) also show fairly strong adsorption capacity for Cd^. The capacity of the former polymer is somewhat stronger for Cd^ than for Hg^ but that of the latter polymer is fairly less for Cd^ than for Hg^.","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"3643","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsumoto,  Masakazu"}]}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"山形大学"}]},"item_3_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00242991","subitem_source_identifier_type":"NCID"}]},"item_3_text_33":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ヤマガタ ダイガク"}]},"item_3_text_34":{"attribute_name":"別言語の出版者","attribute_value_mlt":[{"subitem_text_value":"Yamagata University"}]},"item_3_text_43":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"紀要論文"}]},"item_3_text_44":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper"}]},"item_3_text_45":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_3_text_46":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松本,  昌一"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-08-21"}],"displaytype":"detail","filename":"kiyoue-17-2-01-1_merged.pdf","filesize":[{"value":"743.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kiyoue-17-2-01-1_merged.pdf","url":"https://yamagata.repo.nii.ac.jp/record/852/files/kiyoue-17-2-01-1_merged.pdf"},"version_id":"17f4b42a-22f4-465a-8026-d83703becc51"}]},"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":"二三のポリビニルアルコール誘導体のHg^2+,Cd^2+吸着能","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"二三のポリビニルアルコール誘導体のHg^2+,Cd^2+吸着能"}]},"item_type_id":"3","owner":"3","path":["36"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-09-06"},"publish_date":"2007-09-06","publish_status":"0","recid":"852","relation_version_is_last":true,"title":["二三のポリビニルアルコール誘導体のHg^2+,Cd^2+吸着能"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-25T07:10:52.192200+00:00"}
