【摘要】 阐述了3,5-二溴水杨醛苯甲酰腙(DBSBH)与40多种金属离子所形成的配合物在中性、弱碱性介质中的摩尔吸光系数(ε).其中,与稀土元素所形成的配合物的摩尔吸光系数最大(尤其是钬元素).将DBSBH与镓的配合物用于光度法测定烟道灰中的镓,结果令人满意.更多还原

【Abstract】 Determination of Molar absorptivity of the 3,5-Dibromosalicylaldehyde benzoylhydrazine(DBSBH) with more than 40 metal ions produce complexs,in neutral and weak base medium,among which are Molar absorptivity with greatest value of complexs of the DBSBH-rare eartu elements,especially Holmium(Ho) element.Determination of Gallium using spectrophotomety in the Flue dust with satisfectory result.更多还原
