建立了测定环境中无机锑、锗和甲基锗化合物的方法。在pH1.5的水溶液里,用NaBH_4将这些元素的化合物还原成相应的挥发性氢化物。使用直流放电原子发射鉴定器,锑和锗的测定限是O.4ng。已应用于分析天然水和空气尘粒。检测出了低浓度的无机锑和锗。在所分析的环境样品中,没有检测出各元素的有机金属化合物。存在于矿藏中的锑主要是稳定的Sb_2S_3的衍生物。锗通常是以正四价氧化态的氧化物存在,在溶液中其存在形式是锗酸。Sb的常见价态是正三和正五价,而Ge是二价和
A method for the determination of inorganic antimony, germanium and methylgermanium compounds in the environment was established. The compounds of these elements are reduced with NaBH4 to the corresponding volatile hydride in an aqueous solution of pH 1.5. Using DC discharge atomic emission detector, the limit of determination of antimony and germanium is O.4ng. Has been used to analyze natural water and air dust particles. Low concentrations of inorganic antimony and germanium were detected. In the environmental samples analyzed, no organometallic compound of each element was detected. The antimony present in the mineral deposits is mainly a stable derivative of Sb 2 S 3. Germanium is usually present in the form of an oxide of normal tetravalent form, which is present in solution in the form of germanic acid. The common valence states for Sb are n-tripenta-pentavalent and Ge is divalent-valence
