The relative standard deviation for B at levels of 0.15 and 5 μg were 20 and 4%, respectively. The detection limit was approximately 0.8 ppm for a 0.1 g sample. Satisfactory agreement was observed between the sum of the B values from ionexchange and adsorbed to residual fractions and the reported total B values. Analytical results of B for twenty five geological reference materials, such as igneous rocks, sedimentary rocks, sediments, soils and coal fly ashes were tabulated, and geological and mineralogical features are discussed."},{"@value":"地質試料中Bの溶出挙動を明らかにし存在状態を研究するため,逐次溶解法とICP-AESを組み合わせた分析法を確立し,各種標準試料の分析を実施した.本研究では0.1M硝酸カリウム溶液で溶出する部分を交換吸着態,0.05MEDTA溶液でのそれをEDTA可溶態,0.025MEDTA-0.1Mシュウ酸アンモニウム-0.1Mシュウ酸-0.05Mアスコルビン酸-0.005M塩酸混合溶液でのそれを酸化物態,6M硝酸-1M塩酸でのそれを硝酸-塩酸可溶態,炭酸ナトリウム融解でのそれを残留物態とした.本法によれば,0.1gの試料で0.8ppm以上のBが定量可能であり,0.15～5μgのBの定量における相対標準偏差は20～4%であった.確立した逐次溶解法は地質試料中Bの起源や存在状態を把握する方法として有効であり,各種地質標準試料中Bの分析結果によれば,海底堆積物,マンガンノジュール,コールフライアッシュ中のBは他試料に比べて溶出しやすかったが,火山岩,堆積岩,土壌ではいずれも残留物態で最高濃度が得られ,これら試料中のBは主として火山ガラスや難溶性のケイ酸塩鉱物中に含有されると考えられた."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410001204051083648","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000004505706"},{"@type":"NRID","@value":"9000273006370"},{"@type":"NRID","@value":"9000273026986"},{"@type":"NRID","@value":"9000364786927"},{"@type":"NRID","@value":"9000364790139"},{"@type":"NRID","@value":"9000364790316"},{"@type":"NRID","@value":"9000364786860"},{"@type":"NRID","@value":"9000364790187"},{"@type":"NRID","@value":"9000364790202"},{"@type":"NRID","@value":"9000364790256"},{"@type":"NRID","@value":"9000364790391"},{"@type":"NRID","@value":"9000364790278"}],"foaf:name":[{"@language":"en","@value":"TERASHIMA
