Compared with the cases using borohydride solution alone as a reductant, the sensitivity was enhanced extremely by the addition of dichromate, hydrogen peroxide or persulfate to the acidic solution of lead(II) prior to the injection of borohydride solution. Permanganate also exhibits such enhancement effect in some grade. When dichromate is used together with borohydride, malic acid or tartaric acid should be used as the acid. Various factors affecting the evolution of lead hydride, especially acids (and its acidity) and the concentration of above sensitivity enhancement reagents, were investigated. The determination procedure is as follows: Five to ten cm<SUP>3</SUP> of sample solution was put into a reaction vessel (Hitachi Co., Ltd.), reagents were added, and the solution having one of the following compositions was prepared; (A) 0.25 M malic acid (tartaric acid)-0.025 M dichromate, (B) 0.5 M HNO<SUB>3</SUB> (HCl, HClO<SUB>4</SUB>, 0.25 M H<SUB>2</SUB>SO<SUB>4</SUB>)-1.3 M H<SUB>2</SUB>O<SUB>2</SUB>, (C) 0.3 M HNO<SUB>3</SUB> (HCl, HClO<SUB>4</SUB>)-0.12 M K<SUB>2</SUB>S<SUB>2</SUB>O<SUB>8</SUB>. The volume of the solution was adjusted to 20 cm<SUP>3</SUP>. After the injection of 5 cm<SUP>3</SUP> of w/v NaBH<SUB>4</SUB>, the evolved lead hydride was introduced into nitrogen-hydrogen flame of the atomic absorption spectrometer. The detection limit of the method (S/N=2) is 15, 20, and 20 ng for (A), (B), and (C) system, respectively. The calibration graph was linear up to 1.5μg Pb. Effect of diverse ions on the determination of lead was also examined."},{"@value":"水素化ホウ素ナトリウムを用いる鉛の水素化物発生-原子吸光法について検討した.高感度を得るためには,鉛(II)の酸性溶液に二クロム酸カリウム,過酸化水素,あるいはペルオキソ二硫酸カリウムなどを加え,次いで水素化ホウ素ナトリウムを添加することが重要である.二クロム酸カリウムを併用する場合は,還元後生ずるクロム(III)の水酸化物沈殿を防ぐため,リンゴ酸又は酒石酸を用いるとよい.感度は種々の因子に依存するが,条件を一定にすることにより再現性のよい結果が得られた.リンゴ酸(又は酒石酸)-二クロム酸カリウム-水素化ホウ素ナトリウム系を用いた場合,検出限界は15ng(試料10cm<SUP>3</SUP>),鉛(II)1.0μgの10回繰り返し測定に基づく精度は標準偏差率で2.7%であり,他の系でも同程度であった."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410282679029697153","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020705808"},{"@type":"NRID","@value":"9000020794528"},{"@type":"NRID","@value":"9000004510343"}],"foaf:name":[{"@language":"en","@value":"JIN
