The method for arsenate and phosphate was established by applying automated liquid waveguide spectrophotometry. Because the reaction time for the formation of arsenate-molybdate complex is longer than that for phosphate-molybdate complex, a long Teflon tube submerged in a heating bath was installed in the conventional phosphate flow system. The arsenate was quantified as the difference between absorbances of molybdenum blue dyes with (only phosphate) and without (phosphate + arsenate) arsenate reduction treatment. Contamination was observed in the reagent for arsenate reduction and must be corrected. Linear dynamic ranges up to 1000 nM were confirmed for arsenate and phosphate. The detection limits for arsenate and phosphate were 5 and 4 nM, respectively. Freezing was a reliable sample preservation technique for both arsenate and phosphate. The method for PAs and PP was established by combining conventional persulfate oxidation of PP and the automated liquid waveguide spectrophotometry of arsenate and phosphate. The digestion efficiencies of organic As analogs were >93%. Contamination in the glass fiber filter was negligible. Field tests confirmed that the coefficients of variation (CVs) of 10–19 nM arsenate and 4–151 nM phosphate were 7–20% and 1–25%, respectively, while the CVs of 0.9 nM PAs and 10.2 nM PP were 11 % and 4 %, respectively."}]},"item_3_description_63":{"attribute_name":"研究課題番号","attribute_value_mlt":[{"subitem_description":"15H02802"}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Japan"}]},"item_3_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/s10872-017-0412-6","subitem_relation_type_select":"DOI"}}]},"item_3_relation_13":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher's Version/PDF"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/s10872-017-0412-6","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"日本海洋学会"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://kaiyo-gakkai.jp/jos/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"KAKEN研究課題: 天然放射性リン同位体による亜熱帯海域のリン供給過程の解明"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-15H02802/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"研究代表者: 神田穣太 (東京海洋大学) "}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://nrid.nii.ac.jp/ja/nrid/1000060202032/","subitem_relation_type_select":"URI"}}]},"item_3_relation_28":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"40021269042","subitem_relation_type_select":"NAID"}}]},"item_3_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2017 The Oceanographic Society of Japan and Springer Japan.
