摘要 用铅矾浸提液浸提,室温振荡,滤液测定铅矾中铅的含量。残渣用白铅矿浸提液浸提,室温振荡,滤液中加入适量过氧化氢、硝酸,破坏有机物测定白铅矿中铅含量;残渣中加入方铅矿浸提液浸提,室温振荡,滤液中加入适量硝酸,破坏有机物后测定方铅矿中铅含量;残渣中加入磷(砷、钒)氯铅矿浸提液,室温振荡,滤液测定磷(砷、钒)氯铅矿中铅含量;残渣经650℃灼烧后加入适量的盐酸、硝酸分解剩余的铅,分解完成后的溶液测定铁铅矾(及其它形态的难溶铅矿)的铅含量,从而完成了铅矾、白铅矿、方铅矿、磷(砷、钒)氯铅矿及铁铅矾(及其它形态的难溶铅矿)等不同相中铅的测定。 The content of lead in PB-Bauxite was determined after the sample was extracted with PB-Bauxite liquid,room temperature oscillation.The content of lead in white lead ore was determined after the residue was extracted with white lead ore leaching liquid,room temperature oscillation,adding an appropriate amount of hydrogen peroxide,nitric acid into the filtrate and destroying the organic matter.The content of lead in square lead ore was determined after the residue was extracted with square lead ore leaching solution,room temperature oscillation,adding an appropriate amount of nitric acid into the filtrate and destroying the organic matter.The content of lead in phosphorus(arsenic,vanadium)chlorine lead ore was determined after the residue was extracted with phosphorus(arsenic,vanadium)chlorine lead ore leaching solution,room temperature oscillation.Burned by 650℃,the residue is decomposed by adding an appropriate amount of hydrochloric acid,nitric acid.The content of lead in iron-Bauxite(and other forms of insoluble lead ore)is determined.Then the determination of lead in different phases such as PB-Bauxite,white lead ore,square lead ore,phosphorus(arsenic,vanadium)chlorine lead ore and iron-Bauxite(and other forms of insoluble lead ore)are completed.
